I will be climbing Illimani in Bolivia this summer with Mountain Madness. We'll go up to around 21k feet. I have some questions about my layering and need some help. I've been up to around 18k feet before, but didn't really attempt to dress properly, just put a lot of clothes on! For this trip, I want to do it right. Here's the gear I have...
Base - Under Armor cold gear compression
Soft-shell - North Face Apex jacket
Insulating layer - Helly Hansen Odin Belay OR La Sportiva Pegasus
Hard-shell - nothing yet
Any thoughts on what I have and recommendations on what to change/add would be great!
