Rated 5 out of 5 by from Love Mountain Hardwear sleeping bags! My husband and I have MH 0 degree down sleeping bags and so when my daughter needed a new bag, I immediately looked at MH bags. The quality of products is always exceptional (My husband and I own MH ski jackets, hat, zipper fleece and sleeping bags/pads) The Phantom Flame did not disappoint and has kept my teenager warm on a very rainy trip in Glacier NP and her environmental science school camp trip in Central Washington. I’m so looking forward to her using it for years to come. I will definitely be getting 2 more bags for my other 2 children when they are ready for an adult size bag. ❤️

Rated 5 out of 5 by from Warm bag for a cool lady I've recently started mountaineering with my wife, and we quickly found that she got very cold at night. I got this bag for her as it offered the best combination of (1) weight - or lack thereof, (2) warmth, due to both the materials and design, (3) beautiful colors to make the tent into a home, and (4) a right-side zipper to facilitate cuddles before bed, and minimize drafts from outside the tent. Her very first night at 7000 ft with this bag turned into a 12 hour snooze-fest! I anticipate this bag accompanying us for years to come.

Rated 5 out of 5 by from Best down bag I have slept in This bag takes down to the next level with the 800-fill loft. Love draft collar next to the zipper and by the neck. Pockets inside for my phone/batteries. Comes with a loose mesh storage bag as well as a compression bag. This is my new go to all year bag. I tend to sleep cool so this will be fine for the summer months, perfect for spring/fall, and with some layering will even work in winter. The mummy cut is definitely snug, but perfect for backpacking.

Rated 5 out of 5 by from Best bag I have ever owned. I used this bag on a solo deer hunting trip here in southeast Alaska back in November during our cold snap. I spent nine nights total in the bag with six or seven of those nights with the temps getting down to 20 degrees Fahrenheit. This bag performed great. I did not once get cold and I slept comfortably all night, every night. This sleeping bag really did made a big difference in my trip. I am a larger dude at 5'10", 240 pounds and when I initially purchased the bag I was concerned that I might not fit me. But, it fit me perfectly. There was plenty of room but not too much. I could not be happier with this sleeping bag and I look forward to many great trips with it.

Rated 5 out of 5 by from Under the stars I work as Wildland firefighter on a hotshot crew and this is my go to bag! We rarely use tents and it keeps me warm on the really cold nights. It also keeps me surprisingly dry on the nights we wake up with our sleeping bags sopping wet with dew.

Rated 5 out of 5 by from Cozy and light This bag also offers an excellent warmth to weight ratio. It is very well designed and made. The added water resistance treatment to the down is a real benefit here in the Pacific northwest. I am 6' tall, 175 lbs and the regular fits me just perfectly. Although it is a mummy, the midsection is relatively roomy and doesn't leave you feeling claustrophobic. I would highly recommend this bag. (This review was collected as part of a promotion.)

Rated 5 out of 5 by from Perfect This is my 3rd MHW bag, and I thought my first 2 were amazing, but this one went above and beyond... Lightweight, great fit, smoothest zipper ever. Way more than I could have hoped for. Stoked to put a thousand nights in it.

Rated 5 out of 5 by from Quality Bag Used on an open bivvy on Mt. Adams in Sept. Also used on Rainier, Baker, Hood, etc. No complaints, it does it's job at a light weight. Quality bag at an expected price.

Rated 5 out of 5 by from Great features, super light/compact I love this bag, I sleep warm and used this on a recent trip to the High Sierra where were were hit with rain, hail and snow as well as sleeping on 12 feet of snowpack at 10,000ft a couple evenings in below freezing temps. The q-shield technology really makes its mark when combined with the Ghost UL tent line where condensation can sometimes be an issue. This bag makes up for the minor tent issue by keeping its warmth and drying out lightning quick in the mornings with just a little sun or wind. As a photographer people always ask how I get my batteries to last when camping in winter conditions, it is a constant battle to keep the batteries as warm as possible, so I have always had to sleep with them in my pockets. With the genius interior design of the bag there are not one, not two, but THREE pockets to store small items close to your body's warmth. I was able to store all the electronics overnight and keep them working longer than expected in such cold conditions. Great work MHW. I highly recommend this bag.
