MontBell U.L. Spiral Down Hugger #1

rated 5.0 of 5 stars
photo: MontBell U.L. Spiral Down Hugger #1 3-season down sleeping bag

Tucking into this bag is akin to snuggling up to a cloud. The -15° rating is no lie, and it easily packs down smaller than a milk jug.

Pros

  • Lightweight
  • Compact
  • Warm
  • Cozy

Cons

  • Down not treated

This is a super lofty bag with nicely baffled zippers and entrance and a soft, brushed material that has held up to the few snags I've managed to put it through over the years. The stretch of the spiral baffles is a plus for us fetal sleepers, or even sitting cross legged.

Everyone I've shared my tent with has been jealous of its obvious coziness and I can sleep warmer than all of them, even having to employ the double zipper feature to vent my feet in the footbox/oven.

Even so, I've found it's also surprisingly breathable. It has leached moisture from my tent walls on particularly damp evenings, but nothing that didn't dry out by lunchtime (due to its loftiness).

Warmth-to-weight is amazing as always with Montbell. Stretchy design makes sleeping easy for even the tossiest and turniest of us.

Pros

  • Design
  • Warmth-to-weight
  • Packs down small

Bought mine a while back in Japan and can say after 20+ years of buying bags this is the ultimate bag in my arsenal. Light, warm, stretchy, and packs down to very little, especially if you use a compression sack.

You really can't go wrong with anything from Montbell, but their bags are unreal. Check any and all reviews and they all say the same.

Bag is very light 2 lbs, compresses to fit in Nalgene bottle and warm as can be.

Pros

  • Warm
  • Light
  • Compressible

Cons

  • None

Bought two of these, one for my son and myself. Have used many times on Appalachian Trail and Boy Scout camps in below zero temps. Can not be beat, great bags. You have to get used to the entire bag rotating when you move, you don't twist within the bag, but that's why it is warm.

This is a great sleeping bag: light weight and stuffs down small, also keeps you very warm!

No complaints.
