20oz Soft Flask with Bite Top

For trail runners and endurance athletes who need reliable on-the-move hydration, the 20oz Soft Flask fits snugly in vest pockets and waist belts without bouncing. The pliable TPU body compresses as you drink, eliminating slosh and dead weight, while the high-flow bite valve keeps fluid moving fast without fumbling.

• Holds 20oz (600ml) and fits standard front vest pockets and hydration belt sleeves — no awkward adjustments mid-run
• Durable TPU construction is BPA-free, PVC-free, and handles everything from summer heat to freezing temps without cracking or off-flavors
• Collapses continuously as you drink to cut down on slosh and fluid bounce, keeping your stride smooth over long miles
• Wide-mouth opening makes filling with ice or water fast and cleaning after a muddy run straightforward — no specialty tools needed
• High-flow silicone bite valve delivers quick sips on the move with a self-sealing closure that won't drip in your pocket between aid stations
