What Our Gearhead(R) Experts Are Saying:"I wore the Race 2. 0 on a long gravel sufferfest and honestly forgot it was on my back after the first climb. The No Dancing Monkey harness locks it so tight to your body that there is zero movement even on rough terrain, and the insulated bladder sleeve kept my water noticeably cooler through the hottest part of the afternoon. For anyone who refuses to compromise speed for hydration, this is the pack."The USWE Race 2. 0 Hydration Pack was built for the kind of days that start before sunrise and end when you can barely clip out of your pedals. Whether you are threading singletrack or grinding through a gravel century, the last thing you want is a pack that bounces, shifts, or reminds you it exists. USWE designed this one to disappear. The patented No Dancing Monkey harness uses a 4-point suspension system that cinches the pack firmly against your back without restricting your breathing or range of motion. The ultralight 3D mesh backplate pulls double duty, keeping the pack stable and maximizing airflow so you stay cooler when the effort goes up. At just 230 grams without the bladder, you are carrying almost nothing. The included 2. 0L Elite Bladder tucks into an insulated sleeve that keeps your hydration cooler for longer, and the whole system clicks in and out with a Plug-n-Play coupling that works with one hand. The main fabric is made from recycled ocean plastics with a PFAS-free DWR treatment, so the pack performs as well for the planet as it does for your race.
