Carry everything you need for spirited trail runs with the UltrAspire Revolt Race Pack. This streamlined pack features a Max O2 sternum strap that's bungee bound for maximum range of motion. Perforated foam shoulder straps won't soak you in perspiration when you're running through sweltering temperatures. Along the backside, you'll find a larger top compartment that's ideal for quickly accessing a rain jacket, food, or an extra water bottle. The backside's lower pocket carries the included 18. 5 ounce UltraFlask bottle horizontally, allowing you to hydrate yourself on the move. Two quick access pockets along the shoulder straps are large enough for smartphones, energy gels, and other small accessories. Other shoulder strap pockets include a sweatproof electrolyte pouch and a secure zip pocket for cash and keys.
