Dr. S.'s Review of Marmot Phase 20 Sleeping Bag

Marmot did it right here, folks!! Warm and packs down small; yes, the zipper can be a bit difficult but if you use it carefully, no worries. Took this on the JMT during last summer and at 5’7”, the Regular was awesome!

Pros:

packs down small
warm and breathable for active use

Cons:

Zipper can be finicky
