My Go-To Sleeping Bag for High-Altitude Expeditions
2 weeks ago
My go-to sleeping bag on my recent 8000m expedition to Kangchenjunga. I’m 6'2", 185 lbs, and the long size fit me perfectly with plenty of room to move around. The bag is exceptionally durable and incredibly warm with its 800 fill goose down. The real game changer was the GORE-TEX WINDSTOPPER shell. With condensation inside the tent and occasional water drips, the bag stayed completely dry. Despite its warmth, it compresses down well, making it easy to pack for higher camps. This is without a doubt one of the best expedition sleeping bags available.
