There is a air valve on the top cap so air doesn't escape while blowing up by mouth

It is big and fun to use, but the valve leaks and you gradually lose air.

Worked for a 4 hr float but would slowly loose air

I was completely expecting them to pop or leak air at some point but they never did

Leaking the air at the one time use , but it's saved me great

Has a small hole in it which we didn't know about until we were in the lake and notice we had lost half the air in the tube

Inflated them and only one held air

One worked great, the other slowly lost air

You better have an air pump to blow them up with because you will die if you try to do-it-yourself

The problem is 1 of them has 2 pin holes near the seam and it leaks air

They are also larger than you might think they are--I'm over 6' at 210lb, and the size of the tube meant there was enough air to keep me much higher out of the water than many I've tried before (great if you get to a shallow area)

i took this product on an 8 hour river float and it didn't loose any air.

Still, the air holds tight, no rips or valve leaks, but plenty of fun memories and pics that will last us a lifetime!

Durable tube holds air well very nice all around

and it lost air again

Holds air really well.

It still holds air and everything and losing the mesh netting is not the big of

So I ordered a new one for my upcoming float trip and after about 30 minutes of resting it our at a local creek it seems to me losing air

The inflate - deflate valves would not seal and leaked air out on two units.

this is the second time I have bought a river run from amazon that it lost air immediately… :(

Excellent product, easy to fill with right air pump

I inflated them again and again they both lost the air

Has held air all winter so no complaints

Very little air loss in that time

It was difficult to inflate, and after it was it rapidly lost air

Excellent quality, no air leaks, no dry rot, no holes in tube.

Seems to lose air over the course of the day

However 2 out of 4 purchased did not hold air on first use--and as we didn't blow them up until we arrived, it was too late to do anything.

Holds up very well, never looses air.

Overnight it lost air and had to be inflated again.

solid and sturdy with strong air valve

Holds up very well, never looses air.

This makes it easy to inflate the tube initially or blow more air should you want a firmer tube.

The one I bought on Amazon had a slow leak in it, make sure you don't purchase one from Amazon Warehouse like I did cause although they claimed it was "inspected" I was without a float going halfway down the river cause this thing started losing all its air

My only complaint is that you need an air compressor to blow it up.

The air leaked out the first week of use.

Loses a little air overnight but no big deal.

Lost air not only in

Great functional tube with accessories that work well (cup holder, clip together ropes, one way valve for inflation).It did seem to slowly lose air slowly through the day, I wonder if it was just stretching or naturally will leak or if it actually had a hole/defect.

The only draw back is that they seem to lose air each time we use them

Used it the first time and in less than 5 minutes the seating area and tube separated and now loses air

Easy to fill as well - we use a portable air pump that runs off my truck battery, but if you had a shop vac it available it would be even quicker.

The tube itself was relatively easy to inflate/deflate, however it didn't make it down the river for more than an hour before it had lost most its air

was slowly loosing air over about a 2-3 hour period, disappointed.

Over time, this did rip out the bottoms of 2 of the floats.... but did not rip the seams or cause the floats to lose air

The second one and the head support was leaking air!Keep in mind if you doing any serious river floating

Not one tube lost air or was punctured during the 6 hour rocky river run

A foot/hand pump works best as some electric pumps aren't strong enough to add enough air.

One worked great, the other slowly lost air

One worked great, the other slowly lost air

I did it as fast as I could and still lost air so the floats were maybe 90% inflated once on the river.

Worked for a 4 hr float but would slowly loose air

The next morning, 6 were fine, the other 5 had leaked out all the air.

We got 2 of the river runs but one right away started loosing air after first day first use

Can not get the seal to seal where air gets blown in so air continually leaks from this.

Comfortable, holds air well, and seems relatively durable

one lost air over a day or two but pumped right back up.

Even after dragging them over many rocks, they still held air perfectly.

Thankfully the air and water were warm because the bottom of the raft is a plastic mesh

I believe the company has fixed the cap-seal problem considering none of ours had an issue with leaking out air

Also would recommend getting a electric air inflation unit to pump up the these tubes and to suck air out of them when done using

The double tube did lose some air going down the river

Edit- the tubes dont seem to be river worthy 2 years in a row (losing air through tiny separations at the

The top (square) cap unscrews to a valved system where you can blow air in without it coming back out.

It went over rocks with me in it and never punctured nor lost air

they also have the fast air release and deflate completely in just a few seconds

My son's tube did lose air, but I'm not sure if that's because he was jumping in and out of it so much.

But honestly they felt so flimsy and didn’t keep air that well

All 3 held air very well and none of the fill ports leaked

They hold air very well and the valves are large enough that it is easy to use my home air compressor to fill it quickly

Plenty of room, comfortable and held air well.

We inflate all tubes and this one lost all air once on the river 😥

I got two of these and used them for bobbing in the lake, no river tubing activity and one of them lost all the air during the first use.

First the air valve did not close tightly so some air was leaking during first use

The less expensive tubes lose air and aren't comfortable for adults.

It slowly loses air and becomes a useless heap, with only my 97 lb., gentle 12 year old son using it.

the first deflated just after filling it for the 1st time; the second one lost air (slowly) during the 1st day of use.

It didn't leak or lose any air all summer, and was simple to just hose off to clean.

They are super bouyant and do not lose air and easy to set up

The cold water will cool the air, and the pressure in the tube will go down

The seal around the area where you inflate the tube constantly leaked air and we had to stop multiple times to reinstate

None popped or lost air

and they all are still working great as of the end of last summer!

We use these to float down a local creek/river several times per year, as well as to float on at a nearby lake

Worked exactly as I had hoped, surprisingly comfortable, the cupholders sort of tilt inwards when occupied so don't set a full drink in them or it will spill, the only downside is that the dark coloring will burn your arms when you rest them on the plastic sides if you're floating on a really hot sunny day.

I prefer the double as I feel I get more for my

These are the sturdiest, most comfortable, and convienent tubes I've ever used

My friend almost drowned on a unicorn tube cuz those r unstable and do t have the mesh
