I ordered the longest, widest quilt I could buy because I’m rather tall. (6’3”) It kept me nice and warm all night long. I ordered the 30° quilt and it worked perfect on a 40° night. I can definitely see it keeping me warm in 30° weather. The 10D fabric is very soft to the touch and a lot more durable than you would think for how lightweight it is. The quality that was put into the quilt is insane. Beyond high quality craftsmanship. I’ve never invested more than $100 on a sleeping bag or quilt, but I won’t make that same mistake again. I convinced a friend to purchase the same quilt and he is also extremely satisfied. Definitely worth every penny!
