Built for runners who want hydration that stays out of the way, the Pinnacle 18oz Soft Flask is our pick for vest-wearing trail and ultra runners. Its tapered TPU body compresses as you drink, killing slosh and keeping your pocket tight. The high-flow bite valve self-seals between sips — no drips, no fumbling mid-stride.
- 18oz (500ml) tapered profile fits snugly in front vest pockets and waist belt sleeves without shifting or bunching on the move
- Flexible TPU body compresses continuously as you drink, eliminating fluid slosh and freeing up pocket space as miles tick by
- High-flow silicone bite valve delivers fast fluid without choking down — auto-seals leakproof between sips
- Wide-mouth opening makes filling with ice or water fast and post-run cleaning straightforward — no special brushes needed
- 100% BPA-free and PVC-free construction; available in Finish Lime/Reflective Silver for easy visibility in low light
