Mammut Kompakt Down 3-Season Sleeping Bag: 23 Degree Down

Light and tight.

Don't burden yourself with a bulky bag when you can stay warm and comfortable at night in the ultralight Mammut Kompakt Down 3-Season Sleeping Bag. It's designed to maximize comfort without compromising performance, thanks to its down insulation, Trinity construction, and Ergonomic footbox. It's warm enough to keep you toasty when temps dip below freezing on summer nights in the mountains or autumn evenings in the desert, yet light and compact enough for toting deep into the backcountry on your own two feet.

  • Ultralight and compact bag with an emphasis on comfort
  • Down insulation is incredibly warm, light, and packable
  • Trinity construction enhances warmth in foot and head areas
  • Performance hood allows you to see when closed
  • Ergonomic footbox increases comfort and warmth

Review from one of my fabulous customers who took this on a 12 day backpacking trip from N.Maine to Mt..Katabdin : "Mammut, the product line, is brilliant. We discovered Mammut in Switzerland in late 90s, we have alot. This bag is incredible. Really well made. Two comments: (a) the interior baffles are “rectangles” not trapezoids: so what this means is that there are cold spots since the lower and upper seams are above one another. My older bag which is for winter is constructed of trapezoids: this other bag could go to Antarctica, which brings me to item (b) it is not, in my opinion, a 23 degree bag. It was down to 38 degrees every night where we were and I was pretty cold in the Mammut, so every night I wore wool longjohns, wool shirt, and a hat. (Well, this woolen outfit helped scare off the bears at least.)"
