From a mix of winter and summer rock climbing routes to ice wall ascents and ski mountaineering challenges, the Ascendor 45:50 proves to be as adaptable as the adventurer who wields it. Thanks to its removable features, this pack transitions effortlessly from a robust gear carrier to a streamlined summit pack, perfect for fast and light expeditions.

As the flagship model in the Ascendor range, the Ascendor 45:50 is designed for extended mountaineering journeys. Whether the plan involves resting at a high-altitude bivouac before a summit attempt or navigating a hut-to-hut expedition, it offers ample space to accommodate all necessary equipment.

This lidded pack features a zipped side entry for convenient access to gear and dedicated lower ski loops for A-frame ski carrying. Constructed from durable fabrics—50% recycled material along the sides and base for superior abrasion resistance, and 35% recycled lightweight fabric elsewhere—it strikes a balance between strength and weight reduction. Resistant to abrasions, tears, and water, this rugged pack withstands harsh conditions with ease.

With an array of attachment points and functional features, including dual ice axe carries and hydration bladder compatibility, this pack is the ultimate all-season mountain companion. Its lightweight design is complemented by multiple removable elements, enabling users to tailor the pack’s weight, rigidity, and fit to suit their specific objectives. The spring steel frame and internal HDPE sheet can be stripped out, and the hip belt is customisable with detachable webbing and padding for ultralight days.

The Ascendor 45:50’s close-fitting design promotes freedom of movement over challenging terrain. Its moulded, snow-shedding back panel and side compression straps ensure gear remains securely in place. The pack can be sealed and adjusted with a sturdy metal hook or stripped of its top lid for lighter days, using the large compression flap instead. This flap not only secures the load close to the body for improved carrying comfort but also doubles as a rope strap and protects gear from the elements when the lid is removed.

With the Ascendor 45:50, every detail has been carefully considered. Smartly designed, versatile, and comfortable, it is an exceptional choice for ambitious mountain endeavours.
