Mountain Hardwear has a diverse line of sleeping bags, and one of their more popular lines is the Hotbed series. I recently tested out the Mountain Hardwear Hotbed Flame sleeping bag, which is rated to -7C.
The Hotbed Flame sleeping bag makes use of the company’s well-received, proprietary Lamina technology to enhance loft and get rid of cold spots. The bag sports a mummy shape with a roomier cut and a relaxed fit that efficiently maximizes warmth without too much constriction. The sleeping bag’s fabric has a cotton-like feel that mimics the comfort of your at-home linens. I found the bag to be super warm and great for spring camping. I also found it to be very comfortable, even though I don’t normally like the restricted movement offered by a mummy bag. The upper portion of the bag is sturdy and tear-resistant, making it durable.
Another feature of the unisex Hotbed Flame sleeping bag is a comfort foot box that follows your foot’s natural position. The thermal collar and hood keep the warm air in the bag and stops cold from seeping in. Its face gasket also blocks drafts at the opening of the hood.
For adjusting the hood and chest closure, the Hotbed Flame has single-handed drawcords. It also has a draft tube that is insulated with an anti-snag panel that prevents any cold spots along the full-length zipper. The zipper has double sliders that allow you to open the zippers from the top or bottom allowing for proper ventilation. They also allow you to zip two Hotbed bags together if you by the opposite pair.
Mountain Hardwear’s Hotbed Flame sleeping bag retails for $179.00 and is designed for a camper who has plans to go backpacking or trekking. As a synthetic bag, however, it lacks the ability to compress to a very small size, making it most suitable for car-camping. That said, the synthetic bag has Thermal Q insulation that has good compressibility overall, and maintains superb loft.
Finally, the sleeping bag has a neat little feature in that has a micro fleece-lined stuff sack that allows you to use it as both a pillow and a mesh storage bag.
With a Hotbed Flame sleeping bag, you can rest easy knowing you have a strong sleeping bag to survive any cold night.
