Mountain Hardwear Phantasia 15

I bought this bag after realizing I was a cold sleeper even in the summer. I wanted something to keep me warm all year out in the wilderness. I definitely found it with this bag! Lightweight, soft, 850 down fill, easy zippers, and great hood.

Update: 9/5/2025 I still have this bag and use it on every trip. It is still as good as it was 10 years ago! I love this bag! I just returned from another trip in the Sierras and I was so cozy in my bag!

Bag comes with storage sack seen here.

Stuff sack comes with the bag as seen here.

Puffs up quickly even after being compressed for a while.

Very lofty bag, so puffy and soft!

Kept me warm up in Summerland.

I love this bag! Super soft and warm and zippers actually are a breeze to get in and out of bag in the middle of the night. Great hood, actually fits my head like it should. Nice stowaway pocket for phone or MP3 or tissues. Packs down small. I won't need any other bag!
