An ingenious idea made reality by Exped. Instead of filling mats with open cell foam, Exped
uses 700 cu-in down in their new Down Air Mattress. The result is astounding: The 3.5in thick mat insulates, according to EMPA (Swiss gov. material testing laboratory), three times better than comparable selfinflating foam mattresses of similar weight. This at a mere 29 oz and a packed size as small as lightweight foam mats. The best thing about it, it’s extremely comfortble! The mat can be pumped up with the included pump stuff sack, which prevents humidity from entering the mat, something you wouldn’t want happening with foam mats either. |
