Dynafit designed the Baltoro 42 Backpack for ski touring, ski mountaineering, or occasional autumn basecamping with canyon side-trips. This 42-liter pack carries all your gear to the mountain, and then slims down for quick summit skin-ups.
Outfitted with organization systems to the hilt, the Baltoro 42 backpack gets you and your mountain gear to the top efficiently. The anatomical Airmesh back and breathable shoulder straps keeps you comfy and cool while you're trudging up the hill and the detachable 28L pack becomes your fast and light summit partner.
