Available in 450ml with base or 590ml with base (450ml is designed for the M/L Trailblazer, 590ml is designed for the XL). 

The small TWIST bottle 450 has an optimized easy squeeze thanks to a softer material. The bottle cap has a high-flow valve that is self-sealing, leak-proof and comes with an optional dirt cover, so the mouthpiece stays clean out on the trail. 

These are designed to withstand aggressive trail riding, all while being incredibly easy to get in and out.  We have tested these in bike parks across the USA and are happy to report ZERO bottle drops!
