Cons: Pants fit a little strange where the back is a bit short and will show gluteal crease if not for the length of the shirt. If you have a larger than avg sized bottom, size up. The front of the pants covers my belly so I feel the design is flawed. I'm always pulling them up.Pros: It is warm and cozy. Doesn't strink when washed and dried. Keeps me very warm while riding my bike in 50°F but my arms were very cold skydiving in 55°F. I should have worn another another layer on my arms. I wore the pants underneath my REI pants so legs were kept very warm. This fits comfortably underneath my tight fitting pants/jeans and sweaters so it's perfect for layering if you don't like feeling restricted by coats.5ft 145lbs and this is a medium.I waited too long to wear them so I may not be able to return them at this point, which is fine. I like how it fits besides the back of pants riding low. Feel a large may not fit under my clothes as comfortably. Will just go with another brand for a similar product.I'm 5'10, 133#. I bought Mediums to try and match my long limbs yet slim body frame. The medium top fit me perfectly, however, the bottoms were capri-length on me after I had to hike the butt part of the pants over my backside. I am not blessed with a bodacious booty, so this was slightly disappointing that there was so little space for my butt, but luckily I have tall wool socks to accommodate for the lack of length to keep my chins warm.Despite the lack of length and butt-space in the pants, these kept me warm through over 30 miles of backpacking (hiking and camping) in late-fall in Wisconsin with sub-freezing temps and snow. They kept me very warm, but I just wish the bottoms fit better.I was looking for cold weather work out clothes. I got the set for my husband for Christmas and he loved his, so I ordered the woman's version for myself. It is not thick, so it's good as a base layer. I can run with the pants, but I layer the top with a workout sweatshirt + jacket that I've had forever from target. This set is super soft and comfy! I have been wearing around the house as well. I do wish the bottoms were made so that the back went up a little farther then the front (aka, made for woman hips/butt). Overall, I recommend!Ok, this set is pretty incredible feeling. The material is ultra soft and warm. I’ll be living in it for the next few days with record breaking cold temps coming to my area. There is a little weirdness in the fit around my waist area, which might be a deal breaker for others. I thought about taking a star from that but it FEELS TOO GOOD. Maybe I should have ordered a small...? But everywhere else fits great with the medium I purchased. For reference I’m 5’4, 155 lbs, and pretty muscular legs.Great fit, I layer so I order one size upGot to wear my thermals last night. When I first put them on I was very pleased, they are soooo soft and comfy. Not to tight or to loose, a "just right" fit in my opinion. I think they did a pretty decent job of keeping me warmer than I would have been without them. I'd buy more of them. Way better than the old style long johns for sure.Compre talla mediana y me quedo muy justada la parte inferior no me quedo ahora compro talla L y me quedo muy grande eso no me gustoFor my significant other while we're on outdoor excursions. She loves these.
