Prepare for your climb with high-activity underwear, thermal layers, and breathable outerwear. Pack essentials like rain gear, lightweight trousers, and warm accessories. Choose waterproof boots and consider ice traction. Don’t forget camp shoes and ample socks.
Note: Keep your waterproof shell with you (either wear it or keep it in your daypack) anywhere above 10,000 ft. (3,050 M). At any time of the year, you can become quickly chilled in rain at this altitude and above.
Note: It is important that your hat and balaclava are extremely warm, as much of your body heat can escape from your head.
