This is a must for Canadian winters, or cold night camping. My son was warm all night in a tent, in the Canadian Rockies at 4C weather. There was 0 sweat and he loved the fabric. It is thick but breathable. Have not washed it yet, but unless my review changes, it's a keeper! I am expecting this to hold well when we hit -40.

Product arrived earlier than expected and appears to be good quality. My son says they're very comfortable. Size charts need to be cleaned up, there are 5 different size charts shown throughout the posting leaving it a guess what size to buy, I bought medium for my 9 yr old boy and it's a shade loose.

Bought this set for my son to wear under his soccer uniform. He says it’s very comfy and did a great job at keeping him warm and dry while playing in the rain without getting too sweaty. Washed well. Would buy again. We bought a size up and it fits him well with a little room to grow. If your child is tall or a heavier build, buy the size up.

I bought this set for my son 12 yrs old and he says it is very warm and confortable. He is slim but tall and when I took the measurements it indicated that the medium would fit him but it was too small. I returned it for the extra large and it fit well with a little space for growth. Sizing needs to be updated.
