Wind tunnel testing produced an unexpected result: wearing the Race 2.0 actually improved aerodynamics compared to wearing no pack at all. The pack's profile and positioning create a fairing effect that smooths airflow across your back. At 230 grams without the bladder, USWE built the Race 2.0 as their lightest hydration pack to date, stripping weight from every component while maintaining the stability and ventilation that matter during hard racing efforts.

The NDM 1.0 PRO harness uses a fixed design with 4-point elastic suspension that locks the pack in place without restricting breathing or movement. Unlike adjustable harnesses, the fixed system eliminates extra straps and buckles that add weight and complexity. A 3D mesh backplate with silicone printing keeps the pack planted against your back through accelerations, braking, and technical sections. The mesh construction maximizes airflow where traditional solid-backed packs trap heat—critical during summer races or sustained climbing efforts.

USWE includes a 25-gram insulated sleeve for the 2L bladder, keeping your water cooler for longer when temperatures climb. On extremely hot days, you can ditch the sleeve entirely and fill the bladder with ice, positioning it directly against the 3D mesh so melting ice cools your back as you ride. That flexibility lets you choose between insulated water or active cooling depending on conditions. The bladder features a slider opening for ice and easy cleaning, and reverses fully for thorough drying between uses. The pack fabric carries a PFAS-free DWR treatment and is made from recycled ocean plastics, addressing environmental concerns without adding weight or sacrificing durability.
