what we think
Dan, our resident gear expert, has thoroughly tested the Therm-a-Rest Xtherm NXT on winter wild camps in the Cairngorms as well as an Arctic trip in Kiruna, Sweden. The mat’s advanced insulation delivers excellent warmth, making it a trusted choice for cold weather where staying warm is essential.
Dan found that the mat offers a strong balance of comfort and durability without being too heavy or bulky. It has held up well on rough terrain and provided consistent support throughout extended trips. Although it comes at a higher price point, the performance in sub-zero temperatures makes it a worthwhile investment for serious cold weather campers.
For anyone planning winter wild camps or expeditions in harsh conditions, the Xtherm NXT is a reliable option that helps ensure a comfortable night’s sleep. -
reviews
"Works pretty damn good and sleeps well no matter where you land"
"Super warm, honestly feels like its heated. super lite and super comfortable and makes for an amazing sleep. Had mine for years and it did develop a small leak in a seam so I sent it back for warranty and they sent me a brand new one, love the lifetime warranty."
"This has been the best sleeping pad I've owned for backpacking and car camping. Extremely light, very warm and comfortable. Much quieter than the previous model, which my partner appreciates." -
