4.0 out of 5 stars Good bottles of correct size to do not weight you down
I use two of these bottles in the front straps of an Ultimate Direction SJ Vest in lieu of the the original UD 20 Oz. bottles because I felt these last being too heavy, bouncing and sloshing for me. The back of the Nathan bottles is flat, the shape is narrow, therefore I experience much less bouncing and sloshing (now it's almost zero). No leakages detected.

3.0 out of 5 stars Cheap in price, and unfortuantely quality too
I bought these as a replacement for a bottle that popped out of my Nathan Speed 2 belt and lost. If you have a Nathan hydration belt then you are almost certain to lose one or more of the bottles at some point in time as it is a flaw of their design that there is no bungee cord to make sure the bottles can't slip out of the holsters.

I bought these as a replacement for a bottle that popped out of my Nathan Speed 2 belt and lost. If you have a Nathan hydration belt then you are almost certain to lose one or more of the bottles at some point in time as it is a flaw of their design that there is no bungee cord to make sure the bottles can't slip out of the holsters.

These replacements are marginally bigger at 10 fl oz, vs the original's 9 fl. oz, but they fit the speed 2 just fine and you can't argue at the price. The downside is that the cap is made of a brittle plastic, which means that if one of these flasks pops out of your hydration belt and lands on the cap, then it is likely to crack and split. I have had this happen to two out of my three replacement bottles, but never to the original ones (whose cap is made of a rubberized plastic) despite them falling out countless times.

Best advice I can give is to buy and fix some bungee cord to your Nathan belt so that you don't lose the original bottles in the first place!

The valves are a little hard to pull out (but I think they will be better the more I'll use) and you need to turn your head a little back when you drink (this can be a little difficult while running). This is the only reason why I don't award the bottles with 5 stars.

2.0 out of 5 stars Drippy leaky mess!, 16 April 2015
Verified Purchase(What is this?)
These are shockingly leaky. I bought them to replace one I lost from my waist belt. I can only use one of the three, and even that one is still pretty leaky. Boo :(

They are really good. I bought them to replace ones from a running belt which I'd lost. They hold a nice amount
