MontBell U.L. Super Spiral Down Hugger #5

rated 4.5 of 5 stars

Lightweight, but comfortable down bag that packs down small.


  • Down filled, very light in my pack


  • Down could be a problem if it gets wet

My husband and I bought these bags 3 years ago and have taken them on backcountry trips due to their comfort and weight. Although they are rated at 40 degrees, I have slept in mine when it was 31 degrees and did not get cold. My husband is larger and taller though and says that he does get cold sometimes because there is less "dead air space" when he is zipped up inside. I am short enough that I can put my little inflatable down pillow in the bag and I am not chasing it all night as it stays in the hood. He can't say the same. I am 5'4" and he is 5'11".

We do wash them and put them in the dryer with tennis balls to keep them puffy after a trip. So far no problems with construction. They are well-made and they do "hug" you all night due to the spiral design of the bag.

I bought this sleeping bag for Philmont this summer. I love theĀ  18oz weight but I was concerned about the temperature rating of 40 degrees, would that be warm enough for the nights at Philmont. At Philmont they require you to have sleep clothes, mine are capilene tops and bottoms # 2 I believe.

I did a shakedown hike at Oak Mountain State Park in AL. The first night temps got in the low 30's and I was toasty as I could be! What a great bag! It had plenty of stretch in it, as I tend to move around quite a bit.

The next night was in the 40's and I left it partially unzipped because i was too hot!I highly recommend this bag .

Price Paid: $249

Love this bag.


  • Super light
  • Packs small
  • Stretchy


  • No draft tube

Quality construction, no cold spots, packs down small. I use this with a Sea to Summit 15 degree liner and it's a perfect two-season bag.
