The Quadra SLX-Lite 35 Litre Backpack represents the pinnacle of ultralight design philosophy without sacrificing essential functionality or weather protection. Constructed from water-resistant, durable lightweight fabric, this backpack minimises pack weight whilst maintaining structural integrity across demanding expeditions and extended backcountry use. Weight reduction is achieved through intelligent engineering rather than compromise. A lightweight peripheral frame provides load distribution and stability without the bulk of traditional internal frames, whilst a low-profile ventilated back panel promotes airflow and reduces heat accumulation during sustained activity. This design philosophy ensures comfort during high-altitude pursuits and extended mountain traverses where every gram impacts performance. Weather resilience is comprehensive. The detachable waterproof rain cover provides emergency protection against severe precipitation, whilst the water-resistant fabric offers baseline moisture defence. Padded adjustable shoulder straps and adjustable waist and chest straps work synergistically to distribute load evenly across your frame, reducing fatigue and enhancing stability on technical terrain. Compression straps optimise load management and prevent shifting during dynamic movement. Practical organisation features include an internal slip pocket for valuables, elasticated mesh side pockets for hydration bottles or quick-access items, and trekking pole attachment points for alpine pursuits. Hydration bladder compatibility enables seamless integration of hydration systems for extended expeditions. The EasyPanel™ embroidery access facilitates custom branding or personalisation. Reflective accents enhance visibility in low-light conditions, and the tear-out label permits identification. At 35 litres, this backpack delivers substantial capacity whilst maintaining the lightweight profile essential for serious mountaineers and ultralight trekkers.
