A favorite among the Mountain Hardwear alpine climbing team, the Phantom 0 is our lightest fourseason bag. This snug mummy cut bag is insulated with 800fill down, built from Superlight 15 denier fabric and tuckstitched for durability. The Phantom 0 uses every trick in the book to keep you warm while being as light as possible.
Warm and toasty
I used this bag recently backpacking through the Rockies. We were at high elevations for the duration of the trip and this bag kept me nice and warm on the chilly nights. I'm a cold sleeper and woke up snuggly warm each morning (even my feet which are notoriously like ice cubes). The only complaint I had was having to get out of it each morning!
One great bag..
I am a cold sleeper and own other 0deg. bags and have used them down to 15-17 deg. and was cold and confined all night long. I just took my MH Phantom 0 long on it's maiden trip to the Sierras in 2-3ft of snow on the ground with temps getting down to around 5deg F. at night. I slept toasty warm all night only wearing a base layer and actually had to partially unzip and open the bag to keep from being too warm. The bag lofts up nicely and is very comfortable with plenty of room to move. I am a side sleeper and change sides often throughout the night and never felt confined or restricted. The only things I would like to see improved would be a more water resistant finish as the bag did have some dampness to the shell from condensation by morning and if the bag came with a compression sack instead of just a stuff sack.
