30 Jan Mountain Hardwear Lamina Z Sleeping Bags
The new Mountain Hardwear Lamina Z sleeping bags have some new technology we’re keen on checking out. It uses what Mountain Hardwear has termed (quite aptly) welded Lamina Construction, which is supposed to maximize loft in the insulation and eliminate cold spots. It does, according to Mountain Hardwear by thermally mapping insulation to the coldest parts of the sleeping bag, where you need it most. We’re not sure exactly, just from that description, but we’d be willing to try it out. The synthetic ThermalQ insulation inside compresses extremely well, and holds its loft.
The mummy cut Mountain Hardwear uses on the Lamina Z maximizes weight, without putting any constraints on your movement in your sleep, in case you are one of those who rolls around a lot as they sleep. A comfort footbox gives you a natural foot position. The full-length zipper has double sliders for ventilation, while the face gasket and tailored hood prevents drafts from coming in at at the hood opening. You’ll be warm and toasty in this bad boy.
The outside of the Lamina Z is made from a 30D nylon ripstop, durable and light, with a DWR coating to repel water that finds it way on top. Again, that’s water repellent but not waterproof; it’s never a good idea to let your sleeping bag get wet. The polyester lining on the inside helps wick away moisture. And thank to the lightweight, it packs down easily into the included compression stuff sack for popping in your pack, only adding 2 lbs, one ounce to your kit.
The Lamina Z comes in 4 weights – 34 degrees, 22 degrees, 5 degrees and -15 degrees. There’s no winter weather this thing can’t handle, and you can be assured you’ll be warm all over. You can also grab them in Long and Women’s versions, too. Sleep warm.
