This set is so soft. Fits my son perfectly and keeps him warm. We bought the pair with the hole but if you bought the regular one it would just look like sweatpants, which I wish I would have done.

Nice and warm. Sizing is good. Only downside it has collected lint and the elastic waist doesn't stay in place the elastic moves around which is annoying to adjust for my little guy.

These are great! Super soft, wash and dry well. My 4 year old tried them on and didn’t want to take them off! My kids can’t wait to wear them under their ski clothes. Would definitely buy these again.

I picked these up for my grandson whose a figure skaters. He's 9 years old. The fit, although won't last beyond the next year, is excellent, and the stretch will allow his body to grow. He tells me that on ice, he is rarely cold as he is always moving. He doesn't sweat as the fabric wicks it away. The material is quality... it is thickness that helps him not get scraped by the ice when he falls. Because the fit is so good he is free to work on his jumps and spins without the fabric holding him back. This outfit was well-priced... good as it is a necessary costume for his activity. From what I read... it does what it said it would.

I purposefully bought these a size too big for my 6 year old so that he can hopefully wear them again next winter. He likes that there’s a flap in the front of the pants for doing his “business”, and says they are very warm under his winter clothes. The inside is so soft, so they are very comfy for him to wear… he has very little tolerance for itchy material against his skin so these are perfect. The seems look like they’ll hold up just fine, and the material seems to be of great quality. I’ll probably order a set for my ten year old as well now. Highly recommend as a warm, soft, base layer.

Just got the base layer set for my son. the quality is very good, the only thing is the size a bit smaller than I think. He is 12 years old, and I ordered XL, those are still a bit small on him. Other than that, I am satisfied.

I bought these to keep my daughter warm during our cold Minnesotan Halloween. She has sensory issues to uncomfortable clothing. She loved how these felt! They are very soft on the inside. She really like the thumb hole on the sleeves. They are thin enough to wear under jeans and t shirts. They did a good job keeping her warm while she was outside in 30 degree Fahrenheit weather.
