Arva - ST35 Black Backbag

Part of Arva's technical Ski Trip series, the Arva ST 35 Black is a highly capable daypack designed to transition flawlessly between casual powder tours and intense alpine mountaineering. It balances a generous 35-liter cargo space with a lightweight design, making it the perfect choice for riders who carry a full kit of gear, ropes, and safety equipment.

The pack stands out with its multi-access configuration, utilizing premium, water-resistant YKK AquaGuard zippers to secure both the classic top entry and a wide front panel opening for easy, floor-to-ceiling interior access. Comfort and posture are managed by Arva’s 48 cm Aero-Frame back panel, which features ventilated foam padding and load-lifter straps to distribute heavy hardware weight effortlessly across your shoulders and hips. A dedicated, external front pocket keeps avalanche safety tools neatly separated and ready for quick deployment. For added versatility during casual use, travel, or flights, the padded ergonomic hip belt—outfitted with oversized smartphone pockets—can be completely detached.Key Features
