You could visit Machu Picchu by train like the rest of the tourists, but you'd rather make the trek on foot, and the Mountain Hardwear Women's Ultralaminina 32 Sleeping Bag is the perfect choice for the cool nights and high humidity. The Lamina construction eliminates cold spots and reduces bulk while additional insulation addresses women's warmth needs, which means you really will sleep comfortably down to 32°F. And when the thin high-altitude air kicks in, you'll appreciate that this bag weighs less than two pounds.

  • With an EN upper limit of 34˚F (upper limit refers to the average woman's comfort zone), this bag is best suited for camping in the late spring, summer, or early fall
  • Thermal.Q synthetic insulation is highly compressible, maintains its loft, and insulates better than down if it gets wet
  • Ripstop nylon shell is ultralight and highly wind resistant
  • Performance mummy cut reduces weight and bulk while increasing thermal efficiency
  • Lamina construction attaches the shell directly to the insulation, eliminating cold spots caused by typical baffle construction
  • Comfort Footbox accommodates the natural position of the foot for improved warmth and comfort
  • Ultralaminina weighs in at just 1lb 15oz

Lightweight, small, warm

  • Familiarity: I've used it several times

When this was designed it was top of the line. Now there are some lighter options but this one is still a great choice. Nothing particularly unique or annoying about it, just a nice solid bag. I've used it comfortably down to 15 degrees with a cheap cotton liner and thermal PJs.


  • Familiarity: I returned this product before using it

I an Ultralamina a few years ago for my boyfriend ( for a gift. I've been jealous of his lightweight, small-packed bag since day one. I finally saw this one on Steep and Cheap and grabbed it; however, this one is MUCH thicker, heavier, and does not pack down as tiny. It also seems less "soft." It seems like it would probably keep you warm, but unfortunately I'm not keeping it to find out.

Women's sleeping bags are designed with the fact that women tend to sleep colder than men and so there is significantly more insulation in the women's models than mens. For a woman to feel warm in an equivalent men's sleeping bag, you would have to get a bag that was rated 10-15 degrees warmer. This is why the bag is much thicker.

Is this bag really 1 lb 15 oz? Seemingly...

Is this bag really 1 lb 15 oz? Seemingly the same bag on Mountain Hardware's website is 2lb 8oz.,default,pd.html

I think you need to go with the Mountain Hardwear version. Apparently they have a similar sounding/looking bag called the ultraLAMINA instead of the ultraLAMININA. The Lamina is 1 lb 14 oz. the Laminina is over 2 lbs. Here is the site.,default,pd.html

Thanks Alex, are you saying go with the spec's from the Mountain Hardwear website for the Ultralaminina? The Ultralaminina is the women's version and has more insulation and is indeed over 2lbs, which is why I think the specs here are wrong. I just want to know if I order this bag from Backcountry... what will I be getting? It says this is the Ultralaminina Women's but the specs are for the men's Ultralamina. Will I receive the 1lb 14 oz men's bag or the 2lb+women's?
