After-work singletrack laps leave little time for stops, so the Soft Flask rides in the back of a jersey pocket and comes out for a sip on the move. This collapsible water bottle has a twistable, angled bite valve that makes drinking easy, and the flexible body does not slosh when part-full. What Our Gearhead(R) Experts Are Saying:"The nozzle stayed locked through every root and rock garden, and my jersey stayed dry. I could pull the flask, take a sip, and tuck it back without breaking rhythm."
