Eastern Mountain Sports Mountain Light -20 Sleeping Bag Regular - Mountain Light sleeping bags keep you warm and dry in all four seasons with new DownTek technology, which protects the insulation from moisture in the harshest conditions.

Country of Origin: Imported

Fabric:

  • This technology also reduces baffle material requirements, creating less waste and lighter weight compared to conventional baffle systems
  • 13-baffle foot-box construction for maximum thermal efficiency
  • Nylon taffeta lining for softness and comfort

Insulation:

  • DownTek negates the drawbacks of susceptibility to moisture by applying a micro-thin nano polymer to the down, creating a water repellent insulation that actually floats on water
  • In addition to making the down water repellant, the nano treatment also provides anti-microbial and anti-bacterial protection
  • European goose down retains its insulating qualities longer than synthetics for long-term performance
  • The micro-thin treatment does not affect the fill power or feel of the down
  • 800-fill European gray goose down has excellent loft, compressibility, and breathability
  • Within each of these vertical baffles, FlowGate technology locks your insulation in place, eliminating cold spots and maximizing thermal efficiency

Weather and Wind:

  • Lightweight miniripstop shell fabric with DWR finish is fast drying and wind resistant with a soft hand

Sizing:

  • Full-length two-way zipper with antidraft tube and anti-snag piping
  • Vertical Thermal Channels for rapid transfer and even distribution of heat over the entire length of your body

Webbing:

  • Webbing loops at bottom for hanging and airing out the bag

Pockets:

  • Hidden inner pocket secures small accessories

Features:

  • Compression stuff sack and mesh storage sack included (store loosely for optimal loft and durability)

excellent

I bought this bag last year and have used this bag on many overnights in the adirondack high peaks and the white mountains (many = around 20 nights so far).

It is the first -20 I've owned so I can't really comment on compressibilty and weight. I will say that when compressed it is not that much larger than my ll bean 20 degree synthetic bag.

Warmth- the coldest night I've used it on was probably a few degrees below -10. My car thermometer said -10 the next morning. I was plenty warm wearing a fleece, fleece pants, and base layer to bed, no hot water bottle, only one sleeping pad. I saw a review on here that said it wasn't warm at all... I too have at times been cold in it, but I attribute that more to what I ate for dinner and other variables than the bag. Perhaps that was the case for that reviewer.

The zipper snagging isn't a huge deal- it's just that there's a lot of puff surrounding the zipper. Good for warmth, but requires care when zipping.

Warm and Toasty

My girlfriend and I each slept in EMS Mountain Light -20 degree bags last weekend in Vermont. The temps got down to -6 degree F, and we were both quite warm. We each slept on two sleeping pads, wore fleece tops and bottoms, and wool socks to bed. I never felt the least bit cold the entire night, and actually felt quite warm.

As in the past, I found the bag to be very comfortable. It had plenty of room, even with my boots and other items in the bag with me. I took the bag to Mt Washington, NH last winter and had a similar, positive experience. Not surprisingly, it is a bit bulky, but I look forward to many years or usage during the coldest months of the year.

Kept me warm at minus 15 F in Adirondack

Used on two nights/three days Winter Mountaineering School out of Keene Valley, NY.
As this bag was selected for "emergency bag" for our two summit attempts, it was appropriate in weight but not bulk.
Zipper gets stuck easily and is hard to manipulate when inside the bag.

Negative Reviews:

Not a -20 Bag. O Degree at best

The temp rating is not accurate. If you had this bag in -20 you would freeze. I had it out last weekend at -5, and was not warm, especially in the feet area. I had to put on extra layers and down booties to stay warm. It is light, true, but they skimped on the down to keep it that way I think.
