As a specialized custom hydration pack factory for technical athletic gear, we present this hydration water backpack, engineered for superior comfort and performance in cycling, running, and endurance sports. The core innovation for retailers is the Breathable Mesh Shoulder Straps lined with silica gel, which significantly enhances air circulation and minimizes pressure compared to traditional straps.

Performance Features: The included 2L hydration bladder is food-grade, BPA-free, and leak-proof due to its thickened material and upgraded wide opening design, simplifying maintenance. Crucially, the Insulated Bladder Bag keeps water cold for up to 4 hours. The pack features 3 pockets and an external elastic cord for ample storage of gear and essentials. We specialize in OEM/ODM to customize the insulation, materials, and color (like this royal blue) for your brand's specific needs.
