Fly Fishing Float Tubes: 7 Picks Compared

Our verdict

Top Picks at a Glance

A float tube is an inflatable craft you sit in while you are in the water, moved by kicking with fins; Outcast puts it this way on its float tube page: “You move a float tube by kicking with fins.” Outcast describes its float tubes as “Designed for lakes and ponds,” and several of the tubes here list fly-fishing details such as a stripping apron, a fly patch or a rod holder. This guide compares seven float tubes for fly fishing sold on Amazon from three makers, with each figure as the maker’s page or the model’s Amazon listing states it, and marked when it is the listing. If you are also choosing the rest of your kit, our guides to how to choose a fly rod and fly fishing waders explained sit alongside this one.

Compare the Fly Fishing Float Tubes

Every row is the exact model we link, with figures from the maker’s page or, where marked, its Amazon listing. “Not published” means the maker’s page and listing do not state it. “(listing)”, or “Listing:” in the Capacity column, means the figure appears only in the Amazon listing text for that model and not on the maker’s own product page; where a listing’s text and its detail fields disagree, the review says so.

How We Picked These Float Tubes

What we weighed

• A float tube the maker sells for fishing, in a model the listing identifies. We kept tubes whose Amazon listing names the model, and dropped listings where the title and the maker’s page did not agree on which model it was.
• Stated figures only. Weight capacity, tube weight, dimensions, bladder type and air chambers appear as the maker’s page or the model’s Amazon listing states them, marked “(listing)” when it is the listing; anything a maker does not publish reads “not published”, and we print no capacity of our own.
• Fly-fishing features. Stripping aprons, fly patches and rod holders, where the maker lists them.
• A spread of shapes. U-boat, V-tube, teardrop, U-shaped and round.
• Evidence we could read. Each review says what the source covered and whether it is a maker’s page or an owner’s report.

Sources and how we graded them and what we left out

Sources and how we graded them

Outcast’s and Caddis’s pages are the makers’ own, so they count as the makers’ claims, not independent tests. We found no independent test of any of the seven tubes we could read, so each review rests on the maker’s figures, plus owner reports quoted from reviews customers posted on Caddis’s own page for the Premier Plus 2. Those are the owners’ words on the maker’s retail site, not our findings. The Gymax figures come from the maker’s Amazon listing, because Gymax’s own page shows only a title and price. People we cite from the r/flyfishing thread on buying a float tube are posters unless they say they own a model.

What we left out

We did not link the Amazon listing titled as an Outcast “Fish Cat Cruzer Rowable” tube that states “300 lb Capacity” and “approximately 64 x 44 inches”: Outcast’s own collection page lists the 2026 Fish Cat Cruzer at 250 lbs and 54″ and the OSG Cruzer Max at 300 lbs and 64″, so the listing and the maker disagree on which model it is. Amazon listings for Caddis’s tubes also disagree with Caddis’s pages in places, and each review says where.

Detailed Reviews

Outcast Fish Cat 4 LCS Float Tube, U-boat with foam seat

Evidence: No independent test; maker specs. Source: Outcast (maker).

Outcast’s collection page lists the 2026 Fish Cat 4 LCS at 54 inches long with 12-inch tubes, 16 lb, a foam seat, vinyl bladders and two Boston valves, and says its load capacity “includes the angler and all gear.” Its product page describes the shape in these words: “U-Boat Shape: Provides legendary stability and effortless maneuverability.” It also says “High-Ride Seating: Stays dry and improves visibility on the water” and “LCS Apron System: Integrated line control for cleaner, more efficient casting.” Those are Outcast’s claims about its own tube.

Outcast says who the Fish Cat line is for: “Fish Cat tubes are built for anglers who spend fewer than 25 days a year on the water.” The page lists two Boston valves but does not state the number of air chambers or a width. We found no independent test of this model.

Against the Inspire-LC II, the trade-off is propulsion: this tube has no oars, where Caddis sells the Inspire-LC II with oars. The Amazon offer we linked is the 2026 Moss colour, sold by a third-party seller, Gritr, and shipped by Amazon when we checked; Outcast’s own page showed “Notify me when available” when we checked.

Specs (linked: 2026 Fish Cat 4 LCS, Moss)

• Shape: U-boat (Outcast)
• Length / tube diameter: 54″ / 12″
• Weight: 16 lb
• Capacity: 250 lb (Outcast says this includes the angler and all gear)
• Seat: foam
• Bladders: vinyl; 2 Boston valves; number of air chambers not stated

Caddis Inspire-LC II Float Tube w/Oars, V-tube with oars

Evidence: No independent test; maker specs. Source: Caddis (maker).

Caddis lists the Inspire-LC II at 63″ x 45″ x 24″, 330 lb capacity and 16 lb, and describes “a V-tube design” and says “Custom oars offer full rotation and lock out of the way when not in use.” Its collection page calls it “A hybrid-style float tube with full locking oars” with “above-water seating.” Caddis names and sells it as a float tube, and it has oars, so it differs from a kick-only model. Caddis does not publish the bladder material or the number of air chambers.

The Amazon listing’s detail fields read a weight capacity of 300 pounds and dimensions of 46 x 42, while its bullet text and Caddis’s page both say 330 lb and 63″ x 45″ x 24″; we print the maker’s page figure.

The Amazon page showed CADDIS Sports as the seller when we read it, and Amazon’s product data listed a third-party seller, DriveLine Supply, at a later check, so the seller can change.

Specs (linked: Inspire-LC II Float Tube w/Oars)

• Shape: V-tube with locking oars
• Dimensions: 63″ x 45″ x 24″
• Weight: 16 lb
• Capacity: 330 lb (Caddis; the Amazon detail field says 300 lb)
• Backrest: foam-padded; side storage bags; stripping apron with measuring tape
• Bladders: type and air-chamber count not published

Caddis Pro 3000 Float Tube, Teardrop, inflatable seat

Evidence: No independent test; maker specs. Source: Caddis (maker).

Caddis calls the Pro 3000 “a larger tear-drop design with extra storage and an inflatable water-level seat” and its product page lists “2 main auxiliary equipment pockets, padded stabilizer bar with attached stripping apron, front rod holder, multiple D-rings, and a dry-fly patch,” with “a durable cordura bottom.”

The figures disagree between sources. Caddis’s product page prints “DIMENSIONS: 21.75 x 11.75 x 5.5, and weight is 11.3 lbs.” and no capacity. The Amazon listing text says “56”L x 45″W x 23″H, and weight is 10.25 lbs. Weight Capacity: 250 lbs”, while its detail fields read 10.3 pounds and a capacity of 300 pounds. The table prints the listing’s text figures, marked “(listing)”; the spec box shows Caddis’s page figures beside them. Caddis does not publish a bladder count.

Against the Premier Plus 2, Caddis’s own line is that the Premier Plus 2 has the “same features as the Pro-3000 plus upgraded materials and larger size.” The Amazon page’s buy box showed a third-party seller, Dune Auto Company, when we read it, and Amazon’s product data listed CADDIS Sports as the merchant at a later check, so the seller can change.

Specs (linked: Pro 3000 Float Tube)

• Shape: teardrop
• Dimensions: 56″ x 45″ x 23″ (listing); Caddis’s page prints 21.75 x 11.75 x 5.5
• Weight: 10.25 lb (listing); Caddis’s page prints 11.3 lbs
• Capacity: 250 lb (listing text); the listing’s detail field says 300 lb; not on Caddis’s page
• Seat: inflatable seat and backrest; cordura bottom
• Bladders: count and material not published

Caddis Premier Plus 2 Float Tube, Teardrop, upgraded build

Evidence: No independent test; owner reports. Customer review on Caddis’s Premier Plus 2 page: Premier Plus 2 Float Tube.

Caddis’s page describes a “Tear-drop design” with “PVC bottom, seat, and front tips protect against punctures,” an “Inflatable seat lets you sit high for visibility,” a “Stabilizer bar with a lap apron,” “2 large gear pockets and 2 auxiliary pockets,” “Removable fly patches and rod-holder straps” and “Boston valves for easy inflation/deflation.” The page gives no dimensions, weight or capacity. The Amazon listing text states “56”L 45″W 24″H and weighs 10.3 lbs” and gives no capacity in its bullets; its detail field reads 300 pounds, so we print capacity as not published.

Caddis’s collection page says the Premier Plus 2 is “A premium option with pro-level comfort and durability” with the “same features as the Pro-3000 plus upgraded materials and larger size.” The Premier Plus 2 listing says 56 x 45 x 24 inches and 10.3 lbs against the Pro 3000 listing’s 56 x 45 x 23 and 10.25 lbs, so the maker’s “larger size” is not visible in the listing figures.

One owner on Caddis’s page, who wrote that he has owned two, and that the first wore out and the second is nearly worn out, said: “This model is great! Easy to transport, easy to maneuver, and easy to use ALL day.” The same owner reported a problem: the stitching on the pockets where the stabilizer bar goes in did not last long on either of his tubes, and he added copper rivets at the corners. That is one owner’s account. The Amazon page’s buy box showed a third-party seller, FactorySupplies!, when we read it, and Amazon’s product data listed CADDIS Sports as the merchant at a later check, so the seller can change.

Specs (linked: Premier Plus 2 Float Tube)

• Shape: teardrop
• Dimensions: 56″ x 45″ x 24″ (listing)
• Weight: 10.3 lb (listing)
• Capacity: not published (the listing’s detail field says 300 lb)
• Seat: inflatable seat; backrest; PVC bottom, seat and front tips
• Valves: Boston valves

Caddis Nevada Float Tube, U-shaped with backrest

Evidence: No independent test; maker specs. Source: Caddis (maker).

Caddis describes “a classic U-shaped design” with heavy-duty rip-stop material, double-stitched critical seams and a “comfortable backrest bladder and oversized seat.” Its page lists “2 main equipment pockets, padded stabilizer bar with attached stripping apron, front rod holder, multiple D-rings, and a dry-fly patch,” plus “Fluorescent safety accents” and “built-in carry handles.” Caddis’s page gives no dimensions, weight or capacity.

The Amazon listing text states “46”L 42″W 18″H.” Its detail fields read a weight of 16 ounces and a capacity of 300 pounds; a 16-ounce weight does not match the other Caddis tube weights in this guide, so we print weight and capacity as not published rather than choose a figure. We found no independent test of this model.

Against the High Sierra II, the difference Caddis describes is shape and layout: this one is U-shaped with a padded stabilizer bar and a front rod holder, where the High Sierra II is the “Original Round Design.” The Amazon page’s buy box showed a third-party seller, Dune Auto Company, when we read it, and Amazon’s product data listed CADDIS Sports as the merchant at a later check, so the seller can change.

Specs (linked: Nevada Float Tube)

• Shape: U-shaped
• Dimensions: 46″ x 42″ x 18″ (listing)
• Weight: not published (the listing’s weight field reads 16 ounces)
• Capacity: not published (the listing’s detail field says 300 lb)
• Seat: backrest bladder and oversized seat
• Bladders: type and air-chamber count not published

Caddis High Sierra II Float Tube, Round design

Evidence: No independent test; maker specs. Source: Caddis (maker).

Caddis’s collection page calls it “Original Round Design that is time-tested and durable” and says “Perfect for casual anglers looking for a cost-effective option.” Its product page lists an “upgraded circular design,” a “comfortable backrest bladder and oversized seat,” “2 main equipment pockets, nylon coated mesh working and stripping apron and 20 in. vinyl primary bladder,” “Fluorescent safety accents” and “built-in carry handles.” The page gives no dimensions, weight or capacity.

The Amazon listing text states “Product Dimensions: 42″ Diameter 18″ H (This is a circle), Weight: 6.2 lbs.” Its detail field reads 6 pounds. Neither the page nor the listing text gives a capacity, so we print it as not published and do not estimate one. The listing is a single listing under model HS/2. We found no independent test or owner report we could read for it.

Against the Nevada, the difference Caddis describes is shape and layout: round, with a mesh working and stripping apron, rather than the Nevada’s U-shape with a padded stabilizer bar and front rod holder. The Amazon page’s buy box showed a third-party seller, Dune Auto Company, when we read it, and Amazon’s product data listed CADDIS Sports as the merchant at a later check, so the seller can change.

Specs (linked: High Sierra II Float Tube)

• Shape: round (“circular design”)
• Dimensions: 42″ diameter x 18″ (listing)
• Weight: 6.2 lb (listing)
• Capacity: not published
• Seat: backrest bladder and oversized seat
• Bladder: 20 in. vinyl primary bladder; air-chamber count not published

Gymax Fishing Float Tube 350lbs, Tube with paddle kit

Evidence: No independent test; maker specs. Source: Gymax (maker’s Amazon listing; its own page shows only title and price).

The Amazon listing is Gymax’s own (Gymax is the seller), and Gymax’s website page for it shows only a title and price, so the figures here are the maker’s Amazon listing. It states a size of 58″ x 43″ x 17.5″ and “a strong loading capacity of 350 lbs,” a build of “tough 600D polyester fabric and high-quality PVC,” an inflatable seat with adjustable backrest, a detachable fishing rod holder, a fish ruler, “a detachable aluminum paddle and 2 flippers,” and a manual pump. The listing does not state a weight or a bladder count, and its weight field reads 350 pounds, repeating the capacity. The listing’s warranty field reads “90 Days.”

The listing text we read does not mention fly fishing; the tube is sold as a fishing float tube “for Fishing and Angling.” We found no independent test or owner report we could read for it.

Against the Fish Cat 4 LCS, the difference is what is included: Gymax’s listing lists the paddle, flippers and pump with the tube. Outcast publishes tube length, tube diameter, vinyl bladders and Boston valves on a maker page.

Specs (linked: Gymax Fishing Float Tube 350lbs, model GM2045)

• Shape: not stated
• Dimensions: 58″ x 43″ x 17.5″ (listing)
• Weight: not published
• Capacity: 350 lb (listing)
• Seat: inflatable seat, adjustable backrest
• Material: 600D polyester and PVC

Choosing a Fly Fishing Float Tube

Shape

The makers use five shape words: Outcast’s “U-Boat,” Caddis’s round “circular design,” “classic U-shaped design,” “tear-drop design” and “V-tube design.” A poster in the r/flyfishing thread, Captain_Hammertoe, wrote: “If you do get a float tube, consider getting one of the V-hull tubes instead of the round kind. They’re significantly easier/faster to propel through the water.” The same poster listed what he sees as drawbacks of float tubes: “They’re slow, you have to go backward, and you sit fairly low in the water.” Those are one poster’s views, not a test.

Picks: Outcast Fish Cat 4 LCS Float Tube, Caddis Inspire-LC II Float Tube w/Oars, Caddis Pro 3000 Float Tube, Caddis Premier Plus 2 Float Tube, Caddis Nevada Float Tube, Caddis High Sierra II Float Tube.

Capacity: read what the figure covers

The capacity figures here run from 250 lb to 350 lb where a maker or listing prints one. Outcast says its load capacity “includes the angler and all gear”; the Caddis page for the Inspire-LC II does not say what its figure covers, and four of the five Caddis tubes have no capacity on Caddis’s own page. Gymax’s 350 lb comes from its listing text.

Kick or row

Outcast’s collection page groups its Cruzer models under “ROW INSTEAD OF KICK” with “integrated 2-piece oars”; the Fish Cat 4 LCS is not one of them. Caddis calls the Inspire-LC II “A hybrid-style float tube with full locking oars” and Gymax’s listing includes a paddle and flippers. The Inspire-LC II and Gymax therefore sit apart from the kick-only picks here.

Fly-fishing features

Where a maker lists them, the details for a fly angler are a stripping apron, a fly patch and a rod holder; each review lists which ones its maker names. Your rod choice is a separate decision; our guide to fly rod size and our walkthrough of how to cast a fly rod cover what to match to the water and how to cast. If you wade as well as tube, how to wear fly fishing waders covers layers, boots and fit. One poster in the thread wrote that “Since you are dangling partially in the water your wader quality becomes a bit more important unless it’s warm enough not to have to wear them.”

Float tubes and life jackets

The U.S. Coast Guard’s boating-safety site says: “Though not always required by law, a USCG Approved lifejacket or buoyancy aid should be worn at all times when the vessel is underway.” It also says: “There’s no excuse not to wear a USCG Approved lifejacket or buoyancy aid while on the water!” That page is written for recreational boaters and does not mention float tubes. Read the full text on the Coast Guard’s life jacket wear page.

Frequently Asked Questions

We did not test any of these, so we do not rank them. Outcast calls the Fish Cat 4 LCS its “go-to tube for stillwater,” and Caddis describes the Inspire-LC II as a hybrid with oars and the Pro 3000 as “a larger tear-drop design.” Match the shape, the listed capacity and what is included to how you will fish.

We found no durability test of any tube in this guide. The makers’ words are marketing: Caddis writes “Heavy-duty rip-stop material with double-stitched critical seams” for several of its tubes and “time-tested and durable” for the High Sierra II, and Outcast writes “Rugged construction backed by a 5-year warranty” for the Fish Cat 4. An owner on Caddis’s page wrote that his first Premier Plus 2 wore out and reported the stabilizer-bar pocket stitching wearing out.

Outcast writes: “You move a float tube by kicking with fins.” Gymax’s listing includes flippers and a paddle, and Caddis’s Inspire-LC II comes with oars.

The bottom line
