More like a hug than a traditional hydration vest. Crafted from a custom-engineered warp knit, the Warp Kit Vest conforms closely to the body, providing a secure and comfortable fit without the need for constant adjustments. Every pocket is engineered directly into the fabric, and comes off the knitting machine fully formed and ready to go. Its simplified construction means fewer potential failure points, no stitching to unravel, and no glued seams to delaminate, resulting in a lighter and more durable vest that’s easy to maintain.

The Warp Kit Vest can hold up to one liter of water across two flasks and offers ample storage for essentials like keys, cards, gels, and extra layers. The integrated stretch ensures the vest stays snug, eliminating bounce and enhancing the overall running experience.

The warp kit vest includes two OEM® Soft Flask 500 ml.

One size fits most.

As this is the first product of it's kind, we are still gathering information for extended sizing. The nature of the warp knit fabric means that it should stretch to fit most sizes, but if you have a particularly small frame (if you would normally buy XXS clothing) then this vest may not fit tightly enough to reduce bounce.

Because this piece is garment-dyed, each one is unique — color may vary and dye may appear naturally varied in places.
