Product Details

The SoftFlask Speed is specifically designed to be compatible with the widest range of vests and packs. Replacement or upgrade, the pinch-welded bottom makes loading into pockets a cinch. Its secure, single-handed SpeedFill™ flip top makes filling fast — both water and fuels — and the self-sealing silicone bite valve delivers sips, not drips. And all this weighs just grams.

Reviews Summary
Customers say these soft flasks are easy to carry and fit perfectly in running vests and belts. The wider mouth makes refilling at aid stations convenient, and the collapsible design prevents sloshing while running. Many appreciate the bite valve for easy drinking on the move and note the bottles don't leak. Some find the hand strap uncomfortable or poorly sized, and a few report durability concerns with the cap closure being difficult to snap or the flask failing after minimal use. Overall, users praise the lightweight, compact design ideal for endurance activities and long-distance running.

    Good for what they are

    These bottles will make refilling easier as the bottom portion is slimmer so they slide in the pack faster. However, this convenience comes at a price in that they hold 100 ml. less fluid. Depending on your route, circumstances, etc. this may or may not be a good tradeoff for you.

    Easy filling!

    I love these for the wider mouth - easy filling, no spilling. Definitely add the straw!
