Nathan Pinnacle 4 Liter

No matter how fast or far you run, this vest is built to keep you on top. Designed to be 20% lighter and more breathable than the predecessor VaporKrar and Howe vests. The Pinnacle series fits like a second skin and adds two new kangaroo pockets to the collection of smart storage spaces.

Perfect Fit

Designed to keep you moving comfortably, this vest is lightweight, breathable and has tapered back panels to keep moisture out. The new improved shape has a slightly longer back for efficient, distributed capacity. With just the right chafe-free fit and shape, this is the perfect racing vest!

Smart storage

Thoughtful storage is always within reach, including two new kangaroo pockets that provide access to one side entry and a vertical pocket for larger items such as trekking poles. On the chest there are two water-resistant pockets for a telephone and a pill pocket with whistle. Side pockets provide easy access to larger items and smaller things like keys and food. This vest comes with 2 soft flasks of 650ml.
