Size

While standing with your arms relaxed at your side, wrap a flexible tape or length of string around your chest at its widest point. The tape should go through your armpits and stay parallel with the floor while taking the measurement.

The Traverse is built for those who go loooong—offering a high-performance 20-litre capacity (19-22 Litres, capacity increases with size) in a low-profile, race-ready design. It wraps comfortably around the body for a secure, bounce-free fit and features our updated MaxO2 adjustable sternum system with dual vertical adjustment for dialed-in comfort and zero slippage.

A large rear stash pocket with compression capability gives you fast access to gear, while an externally accessible, insulated reservoir sleeve makes quick refills easier than ever. The main compartment offers a wide zippered opening, plus an internal pocket with secure storage.

The Traverse is pole-quiver compatible on both sides and includes extended side pockets that reach toward the back for massive storage. Front pockets are symmetrical with dual bottle pockets; special compression stitching ensures bottles fit snug and stay secure, while cord locks offer added retention.

Two zippered top shoulder pockets provide quick-access storage, while two zippered layered front pockets feature padding, air mesh for added comfort, and a sweat-proof liner to protect sensitive items. Together, these details make the Traverse the ultimate blend of capacity and race-day performance.

Lumen 600 V3

This light is lightweight, comfortable and bright!, I used this in a 12 hour night race and could keep the brightness as high as I wanted (because the batteries are cheap and easy to change). It lit the trail well and allowed me to run at my pace (did not need to slow down for visibility).

Zygos V4.0

This vest is AMAZING!! I’ve had many vests over the years but this one beats them all, hands down. I love the placement of pockets, materials used and the overall thought of design that will be long lasting and comfortable at the same time.

Nucleus Vest

Love the design with easy front bottle and phone access. I am short with short arms and love that it’s just an easy grab upfront and super easy to put back in place. Love the magnetic pickers for key fob and nutrition. Such an innovative design and UltrAspire nailed it.
