UltrAspire Traverse Hydration Pack

The Traverse is built for those who go long—offering a high-performance 20-liter capacity in a low-profile, race-ready design. It wraps comfortably around the body for a secure, bounce-free fit and features an 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. Available in five sizes for a precise fit.
