At the amazingly low price of £25 this self-inflating mat costs less than some closed cell foam pads. It’s reasonably light too and suitable for year-round backpacking as it’s filled with solid foam and so should insulate well on frozen ground and snow.
As it only arrived in mid-May I haven’t been able to test it in winter conditions but I have found comparable mats warm in sub-zero temperatures. Alpkit’s R-Value of 4 also suggests it’ll be warm in winter though this is only an estimate as the mat is so new Alpkit hasn’t finished testing this. In design the Base 120 is a conventional rectangular self-inflating mat. It inflates and deflates quickly and is quite compact when packed. Comfort is good. The polyester shell fabric is a little slippery on silnylon groundsheets but this is a very minor complaint. If the length isn’t enough there is the full-length Base 180 which weighs 870 grams and costs £30.
