Nathan Pinnacle 14oz Soft Flask Handheld - Grip-Focused Hydration

In this review of the Nathan Pinnacle 14oz Soft Flask handheld, the bottom line is simple: runners and hikers who prioritize a secure, no-grip fit and lightweight, collapsible hydration will appreciate this carry. The Pinnacle combines Nathan's Exo Shot soft flask tech with a breathable, ergonomic mesh strap so the bottle stays stable while allowing a relaxed hand. The expandable pocket and easy-release soft flask make it a practical choice for long training runs, marathons or day hikes where comfort and quick access to a gel or keys matter most.

Key Features

• 14 oz soft flask: A 414 mL BPA-free flask holds enough fluid for many training runs while collapsing as you drink to reduce bounce.
• ExoSpine support: The proprietary interior ExoSpine adds rigidity to the soft flask for a superior hand feel and more controlled handling.
• Grip-free mesh strap: Ergonomically designed strap contours to the hand so users can run without a tight grip and still keep the flask steady.
• Quick-release flask: The soft flask removes easily from the sleeve for fast refills or cleaning between outings.
• Expandable stash pocket: A small wrap-around pocket stretches to hold gels, keys or a credit card for quick access on the move.
• Lightweight construction: With soft flask installed it weighs roughly 2.54 oz / 72 g, minimizing added weight during long efforts.

Who It's For

The Nathan Pinnacle is ideal for runners, trail runners and fast hikers who want a low-profile handheld that feels secure without squeezing. Those who value lightweight gear, a soft flask that collapses as it empties, and a quick-access pocket for nutrition will find this tailored to their needs.

It is less suited to athletes who need very large volumes of water or want to carry multiple bottles and larger gear; ultrarunners or multi-hour hikers who require liters of capacity should consider hydration vests or packs instead.

Pros & Cons

Cons
