# Nathan's Pinnacle Soft Flask Handheld 18oz

## Ditch the Bottle. Keep the Hydration.

Traditional handhelds are bulky, awkward, and constantly remind you they're there. The **Nathan Pinnacle Soft Flask Handheld 18oz** takes a different approach — a grip-free, ergonomic carry system that wraps around your hand so naturally, you'll forget you're holding anything at all.

The 18oz BPA-free Nathan x HydraPak soft flask features ExoSpine™ technology for a structured feel when full and a clean collapse as you drink — no slosh, no awkward shifting, just smooth hydration on the move. The breathable wicking mesh strap keeps your hand cool, and the expandable stash pocket handles gels, keys, and small essentials without getting in the way.

### Built for Marathons. Ready for Trails.

Whether you're racing 26.2 or exploring a new trail, the Pinnacle Handheld gives you the confidence of carrying your own hydration without the burden of a vest or the annoyance of a rigid bottle. One size fits most, and the soft flask removes easily for refilling and cleaning.
