Osprey's Mutant 22 has evolved into the ultimate climbing pack, designed for year-round ascents, yet still remaining a great choice for alpine hiking too.

Active winter climbers will welcome the snow-shedding backpanel and dual ToolLock™ system, letting you quickly and securely attach your ice axes.

When summer arrives you will benefit from the EVA die-cut ventilated shoulder harness and the ability to strip 120g from the total pack weight by removing any features you won’t need.

• Snow-shedding backpanel and low-profile harness
• Dual ToolLock™ ice axe attachments
• Sternum strap with emergency whistle
• Under lid rope carrying system
• Internal hydration sleeve
• Removable framesheet
• Dual front daisy chains
