Development for this vest began during Satisfy Pro Michael Versteeg’s Colorado Trail Fastest Known Time attempt. Besides needing storage capacity for hydration and nutrition, he needed something ultralight, breathable and that wouldn’t cause any chafing or discomfort on segments between crew-accessible aid. Because nothing existed that excelled at all of these points, we decided to make it ourselves.

Constructed with our proprietary Justice™ fabric and reinforced with Cordura®, this hydration vest is durable with multilinear stretch to accommodate dynamic movement and is comfortable even against bare skin. With 5L of storage capacity and a versatile 8-pocket system, this piece of Satisfy equipment will sustain you on trips of long duration and ultra endurance events.

- Justice™
Our proprietary Justice™ technology was developed in house. This unique synthetic fabric is produced in France by a natural silk maker whose business was founded in 1839 and pivoted in the 1960s to technical and elastic yarn manufacturing. Borrowing from medical technology, Justice™ is highly durable and resilient, but has a feel of silk and an incomparable lightness. It stretches naturally in every direction, following the body movements while staying breathable. Justice™ dries astonishingly quickly, preventing bacteria from mixing with your sweat and staying odor free.

- Cordura®
Exceptional strength and resistance to abrasion, tears, and punctures, with its ability to withstand harsh conditions and intense use, Cordura® is the best choice in terms of durability and reliability.
