Nathan Pinnacle FeatherLite Hydration Vest – Ultra-Lightweight Running Vest with 14oz Flask

Meet the Nathan Pinnacle FeatherLite Hydration Vest

Designed for runners who want to stay lightweight and agile, this vest pairs feather-light construction with smart storage. Weighing about 4.4 oz without the flask and 5.5 oz with it, the vest delivers a barely-there feel that lets you focus on pace and terrain. The shell uses breathable power stretch mesh and stretch woven fabric to flex with you on road and trail, while a longer back promotes a secure, comfortable silhouette.

Design for movement

Bounce-free stability comes from a secure front fit and adjustable side straps. The vest holds its shape without restricting your stride, and power mesh shoulders keep air flowing as you pick up the pace.

Hydration on the go

Stay refreshed with an integrated 14 oz Nathan x Hydrapak Soft Flask that slots into front pockets. Bottle pockets accommodate flasks or bottles up to 20 oz so you can choose your preferred size.

• Front adjustability minimizes bounce for road or trail running.
• Dedicated pockets support up to 20 oz bottles for convenient hydration.

Secure storage for essentials

The 1.5 L back pocket with a right-entry zipper offers ample space for a jacket, hat, or valuables. Keeping your essentials close helps reduce clutter and maintain balance during long sessions.

• Back pocket capacity suits longer runs and cooler weather layers.
• Right-entry zipper enables quick access to items while moving.

Who it suits

Designed for both men and women, this vest blends a secure fit with adaptable sizing, letting the vest conform to your shape for efficient training across terrain.
