Mountain Hardwear Women’s Lamina sleeping bag: first impressions

The Mountain Hardwear Women’s Lamina 15°F / -9°C sleeping bag includes extra insulation in key areas such as the torso and the feet to keep you warmer, which along with a narrow foot box and small, adjustable hood, are features designed to really help seal in warmth on chilly nights.

While at 1.38kg it’s not super lightweight, this bag is still packable enough to work in a larger rucksack for wild camping or mountain adventures, when the warmth is very welcome (see also: The best three-season sleeping bag).

The Lamina is also available in different lengths and with various zipper locations. If you need something for more extreme mountain temperatures, there’s a unisex version of the Lamina rated down to a whopping -26C, or if you’re after a more casual bag for summer, there’s a female-specific version rated down to -1C.

In the field

If you love camping adventures far from the beaten track but struggle to stay warm in cold conditions, the Mountain Hardwear Women’s Lamina is our pick of the pack (see: Best women’s sleeping bags). The extra padding and female-specific design elements really work, and this was one of the snuggest and most streamlined sleeping bags we’ve tested in this category.

That narrow footbox and slim leg area are ideal for keeping warm, but don’t leave much room for manoeuvring – restless sleepers and larger women may find this part of the Lamina’s design too restrictive for them (there’s more about finding the right-shaped bag for you in our Types of sleeping bag article).

Overall, however, with the level of warmth it supplies, the thought that has gone into the female-specific the design, and the versatility of options available, it’s a great choice for more adventurous women campers.
