Blaster Bite valve
GO FEVER RUNNERS- LOVE it, although I do have a nasty tendency to bite hard on bite valves and this caused a premature replacement, it's well thought design, it's a bit tricky to clean. The clip is a nice add cause the way I mount it, it's close enough to sip.

Thanks Stephen! Did you know you can take it completely apart? It's easy to do, just pull off the bite valve area, pop out the blue insert, and then it's super easy to clean!
