Waterproof Breathable Lightweight Hydration Pack

Measuring 45 x 28 x 15 cm and weighing 680 g, this hydration pack uses waterproof polyester fabric with welded seams and a breathable 3D mesh back panel. It holds 12 L total volume, including a dedicated sleeve for 2–3 L hydration bladders (reservoir not included), two side stretch pockets for 750 ml bottles, and a zippered front compartment for keys, phone or nutrition. Shoulder straps feature S-curve ergonomics and soft padded contact zones; chest strap is fully adjustable with magnetic clasp. Reflective piping enhances visibility in low-light conditions common across UK morning/evening commutes. The roll-top closure with dual magnetic buckles offers fast, secure access and enhanced weather resistance. Internal organisation includes a key hook and internal slip pocket. All stitching is bar-tacked at high-stress points for longevity under repeated loading. Designed for users who demand consistent performance across variable UK conditions—whether navigating rain-slicked city streets on a commute, maintaining rhythm on tempo runs, or managing gear and fluids on undulating countryside trails without overheating or bulk.
