Quench your thirst with this 500 ml wide-mouth soft flask that’s built for easy filling, reliable hydration, and a secure fit in our running vest-style packs. Constructed from 0.25 mm clear TPU film with pinch-weld construction and a proprietary tapered pinch-weld bottom, it’s designed to fit wide, short vest pockets while remaining lightweight and flexible. A 42 mm nozzle with an oval flange and 42 mm non-locking bite-valve cap with a silicone-sheathed, high-flow bite valve allows for easy drinking and automatically seals after each sip to prevent drips or leaks. The compressible design shrinks as you drink, reducing slosh, while the soft material conforms comfortably to pack pockets and packs down small when empty.

KEY FEATURES:

• Bite Valve – soft, high flow bite valve auto seals after each sip to eliminate drips and leaks.
• Vest Pack Fit – lightweight and slim design, soft material conforms to vest pockets.
• Compressible – flexible design shrinks as you drink to reduce water sloshing around.
