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.

Made For Fit — Soft material and an innovative pinch-welded base creates a low-profile tapered flask — designed to fit almost any vest, belt, or pack pocket.

High Flow — Easy to drink bite valve auto-seals after each sip, eliminating annoying drips.

Speedfill™ Cap — Designed for fast filling - flips open for quick refills and snaps closed for leakproof transport.

Large Opening — 42mm opening lets you fill the flask easily with ice and drink mixes.

Compressible — Flexible design shrinks as you drink, minimizing water movement.
