Multifunctional Breathable Sports Hydration Backpack

This sports hydration backpack offers three classic colors of gray, black and blue. It meets different buyers’ style preferences and matches sportswear perfectly for outdoor trips.

Polyester material forms both the outer shell and inner lining of this backpack. The firm fabric resists wear, and the ultra-light whole pack avoids heavy pressure during long-time carrying.

3D honeycomb breathable mesh covers the back panel and shoulder straps. Air flows freely to release heat quickly and stop sticky sweat during exercise.

This backpack sets up separate storage spaces. The main compartment holds a hydration bladder inside. Side pockets on straps fit 250ml soft water bottles and energy gels. Zipper pockets safely hold 6.6-inch mobile phones, and stretch pouches keep snacks, keys and small items.

Wide curved shoulder straps fit shoulder shapes well. Adjustable chest buckles and bottom webbing let users customize tightness. The pack stays steady without big shakes while running or cycling.

KAM brand smooth zippers equip the pack, and reinforced stitching prevents thread breakage under pull. Orange emergency whistles and reflective strips on straps raise safety for night running and night hiking. The 21×7×38 cm compact pack fits body curves and folds easily for cycling, hiking and mountaineering.
