I decided to get a quilt as I was a side sleeper. I am section hiking the Te Araroa Trail in New Zealand and so needed something that covered all the bases. I got the -5°C quilt as I had experienced snow on the trail. Since getting the quilt I have had to sleep by the sea in 25°C heat but was able to pull the end up off my feet and top down lower on my torso. I have also slept in an alpine area where the temperature was down to 3°C with the foot box zipped up and the top around my neck cinched with no extra layers of clothing. Both times I had a great night's sleep. This along with a decent sleeping pad is the perfect sleep system for me. Thank you Debra your quilts are the best !!!
