Hydrapak SoftFlask Speed 500 ml

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.

• Vest-pack fit provides bounce-free stability and a flexible flask shoulder to prevent chafing so you can focus on FKT's and PR's
• Soft, high-flow bite valve auto-seals after each sip, eliminating annoying drips
• 42mm opening lets you fill the flask easily with ice and drink mixes.
• Made of ultra-durable, abrasion resistant TPU & RF welded seams for superior durability and elasticity
• 00% BPA & PVC free, wide working temperature range (can be frozen - max temp 60° C / 140° F)

*BOTH PRODUCT OPTIONS ARE THE SAME FLASK, ONE COMES WITH YELLOW STRIPES, ONE WITH WHITE
