Very comfortable at high elevation

Slept in my new NZ 20 bag at 10,300 ft. elevation this week, and it was wonderful. It fit well in my backpack, and I never got cold, even with those high elevation temps. Thank you Near Zero!

NZ 20 Degree bag

I bought this bag for my daughter to take to Philmont for her Cavalcade trip. She loved it because it was light and compact and fit very well in the small stuff sack they were given. Took less room in the panniers on the pack horse. It was chili at certain camps they stopped and and she said it kept her cozy sleeping.

Light and Compact

This has the same fill as my expensive bag, is just as light and packs down smaller. I love the stuff sack. I also love how roomy it is inside the bag. I don’t feel confined. It is attention to detail and kept me warm in the low 40s and high 30s.
