12L Ultralight Waterproof Running Backpack

This 12-litre outdoor backpack measures 40 × 25 × 9 cm (15.7 × 9.8 × 3.5 in) and weighs just 480 g (16.9 oz). Constructed from a durable blend of tear-resistant nylon, spandex, polyester and PEVA, it features a waterproof outer layer and hydration insulation lining. The design includes a built-in hanging strap for a water bladder (not included), reflective strips for low-light visibility, and fully adjustable shoulder, chest and waist straps for secure fit. Mesh-covered padded back panel and ventilated shoulder straps enhance airflow during prolonged activity. Two zippered waist pockets provide quick access to phone or small essentials, while a pipe-fixing rope on the shoulder strap helps route and stabilise a hydration tube.
