Nathan | Pinnacle Soft Flask | 18 oz | Black/Reflective Silver

Stay hydrated through every mile with the Pinnacle Soft Flask 18oz Handheld, a lightweight running water bottle designed for runners who want premium hydration and all-day comfort. Ideal for marathon training, long runs, trail running, hiking, and endurance events, this handheld bottle combines a larger fluid capacity with an ergonomic, distraction-free design.

Featuring advanced ExoShot™ soft flask technology, the 18-ounce 3D flask compresses as you drink, reducing bulk and eliminating water sloshing for a more comfortable carry from start to finish.

The updated carrier includes a breathable, grip-free mesh hand strap that naturally contours to your hand, allowing you to run comfortably without gripping the bottle. This ergonomic design reduces hand fatigue while keeping hydration easily accessible throughout your workout.

A convenient wrap-around storage pocket securely holds running essentials such as energy gels, keys, or other small nutrition items, making it easy to fuel and hydrate without slowing down.

Whether you're training for your next marathon, exploring the trails, or logging high-mileage days, the Pinnacle Soft Flask 18oz Handheld delivers lightweight comfort, secure storage, and reliable hydration to keep you performing at your best.
