12L Adjustable Insulated Outdoor Pack

With a 12-litre internal volume and compact footprint of 23 × 10 × 43 cm (9 × 3.9 × 16.9 in), this hydration backpack is engineered for agility and adaptability across varied outdoor environments. It weighs only 0.36 kg (12.7 oz), contributing to reduced fatigue on long ascents or fast-paced trail runs. Constructed from robust nylon fabric, it provides dependable water resistance against drizzle and splash, plus strong resistance to scuffing from rough terrain or gear contact. The insulated bladder compartment supports consistent fluid cooling — performance confirmed under typical UK spring/summer field conditions — though the bladder is sold separately. Storage versatility comes from a zippered front pocket, two stretchable mesh side pockets, and an adjustable cord for external attachment. Comfort is prioritised via breathable mesh overlays on all contact surfaces — shoulder straps and full back panel — preventing hot spots and moisture lock-in. Fit customisation is achieved through independent adjustment of shoulder, chest, and waist straps — accommodating broad anatomical variation without requiring gender-specific models. Reflective trim improves passive safety during low-light travel. Designed for compatibility with hiking, cycling, climbing, camping, and running applications.
