UTOBEST 5L Unisex Hydration Running/Cycling Backpack

Unisex running backpack with a separate bladder compartment, two front flask pockets with secure loops, a zipper pocket for your phone, and various pockets for keys and other items. (Bladder and flasks not included.) Reflective strips and a rescue whistle enhance safety. Made of mesh fabric and nylon, which is stretchy and breathable. Adjustable strap design for easy adjustment and outstanding stability, reduces bounce and ensures a great fit while running. A great backpack for those new to running or wanting to try a running vest. No longer needed as I’ve upgraded to a Nathan brand running vest.
