Great hydration on the go
Works as described. I've never had one before but it works perfectly. I can put the bite tube under my helmet and drink with one hand while I ride, no problem (and I'm a total beginner...4 days on the bike). It has a really large fill opening, like 4" in diameter. I'm guessing that's so you can really reach inside and clean it with dish soap so it doesn't grow wildlife inside, but I'm not sure.
