USWE Race 2.0 XS Hydration Pack The USWE Race 2.0 XS Hydration Pack isn’t just about carrying water; it’s about making you faster. Rigorous testing has proven that the pack’s streamlined profile improves your aerodynamics, offering less wind resistance than riding without a pack. To manage heat during high-intensity efforts, the pack includes a lightweight insulated sleeve to keep your hydration cool in sweltering conditions. Alternatively, for those scorching summer races, you can remove the sleeve and place an ice-filled bladder directly against the 3D mesh backplate, allowing the pack to act as a cooling heat sink against your spine while you push your limits. Stability Meets Environmental Responsibility Crafted for a precision fit, the fixed harness utilises a high-ventilation 3D mesh and a strategic silicone print to ensure the pack remains rock-solid on your back, even during technical descents or out-of-the-saddle sprints. You can ride with total confidence knowing your gear is as eco-conscious as it is high-tech; the main fabric is constructed from recycled ocean plastics and features a PFAS-free DWR treatment. By choosing the Race 2.0 XS, you are investing in the most breathable, stable racing pack on the market.
