I used these for my son who wanted to be a minion for Halloween. They were perfect! Bonus points for being extra warm. Then we used them as long John’s for when it snowed out. Would definitely purchase again. My son even slept in them as PJ’s so we definitely got our money worth from them.

I purchased these in XL dark navy blue. I'm 107lbs female 5'5 And these fit great! The sleeve on the top feels a bit short but they do come to a comfortable place so that might just be a personal preference. They are extra soft. The opening in the bottoms is sewn closed which is perfect. I'm wearing them to bed as I type this and couldn't love them more. Color is great. Fit is perfect and I'm nice and warm. Win win win.

Soft, stretchy, comfortable. Great base layer under jeans, rain pants, T shirts, etc! Often my kids will wear these as Pajamas and then just get dressed in the morning by pulling their clothes ontop. Keeps them warm. Great quality and price
