Built for runners and hikers who carry their hydration in-hand, the Pinnacle 18oz is our pick for hot-weather efforts where a cold sip actually matters. ExoSpine technology keeps the flask from collapsing in your grip, while double-wall insulation holds fluid temps longer than a standard soft flask. The mesh strap and built-in pocket round out a clean, no-fuss carry.
- 18oz (535mL) capacity with double-wall insulation — keeps fluids noticeably cooler during long efforts in Southern heat
- ExoSpine technology gives the flask a firm, stable feel in hand so it doesn't pancake mid-squeeze
- Lightweight breathable mesh strap wraps the flask for a secure, hand-friendly carry with minimal fatigue
- Expandable exterior pocket fits keys, a gel, or a card — enough for a solo run without a vest
- BPA-free, food-grade materials; collapses as you drink to cut sloshing and pack down when empty
