Lowe Alpine Halcyon 35:40 Medium



Whether you’re scaling glaciers or projecting a summer rock route, the Halcyon 35:40 alpine mountaineering pack has everything you need for a day moving in the mountains.

Born from Lowe Alpine’s vertical heritage, the Halcyon 35:40 is a mid-volume, traditional mountaineering pack designed for the extraordinary.

With features including a rope compression system, pick retainer panel and reinforced ski slots, you can carry your kit securely over rock, snow or ice. An extendable lid increases the volume by 5 litres, while a stiffened weather flap/compression system aids stability. A lid pocket and zipped side entry keeps kit organised and accessible.
