The Osprey Variant 37 is a versatile backpack designed specifically for ski mountaineering and ice climbing. Here are some key features of this pack:

1. Materials and Design:

   • Unlike most Osprey packs, which use heavy-duty fabric on the bottom and a lighter fabric on the body of the pack, the Variant 37 is built entirely from mid-weight 210-denier nylon.
   • It comes in two color choices: a two-tone black and gray version with blue accents, and a high-visibility red-and-orange colorway called “Diablo Red.”
   • Winter climbing-specific features include A-frame ski loops, a rope compression strap, a heavy-duty crampon pocket, and dual ice axe holsters.
   • The firm foam backpanel is designed to shed snow and ice.

2. Weight Capacity:

   • The Variant 37 is designed to carry much more weight than similarly-sized packs. Osprey rates its weight capacity at 35-40 pounds.
   • To achieve this high weight limit, the pack employs a 6mm aluminum frame and a 1.5mm thermoplastic framesheet.
   • The detachable hip belt and integrated shoulder straps are heavily padded with thick foam.

3. Fit:

   • Its tall, thin shape allows excellent freedom of movement, and the foam back panel, hip belt, and shoulder straps all feel snug and secure.

4. Versatility:

   • The Variant 37 perfectly fills the niche between summer day packs and overnight packs.
   • Whether you’re going on an alpine day trip, cragging, or a summer weekend backpack, this pack has you covered¹.

So, if you’re a ski mountaineer or ice climber looking for a reliable and functional backpack, the Osprey Variant 37 might be just what you need!
