Great baselayer to wear under drysuit for kayaking
First, I'm 5'7", 250 lbs, 38-40 waist, 50 inch chest, XXL fits well and comfortable, though the sleeves and legs are a bit long. Not a big deal, they can be bunched up. The Fleece lining is very comfortable against my skin. I wear this under my drysuit. While in the water I found the sleeve of my drysuit had a leak. As the cold water came in, the sleeve of this base layer got pretty wet. The wet sleeve felt cold, but it still kept me fairly warm and didn't absorb much of the water, helping me to stay warm. The rest of me stayed comfortably warm in the 40ยฐ water, even though the drysuit itself didn't do much for warmth, it just kept me dry. **UPDATE** I have now worn this for three sessions of rolling practice in my kayak. I still have a small pinhole leak somewhere in the back panel of my drysuit, but it doesn't leak too much so I don't worry about it. This baselayer is still keeping me warm as the only thing I'm wearing under my drysuit in 45ยฐf water, even when slightly damp. This isn't just while sitting inside the kayak, but also while submerged upside down and while swimming during a wet exit. This really is a great mid weight base layer, and one that any kayaker should consider for under their drysuit! If you're going to be in water any colder than this though, especially if the air temperatures are cold, I would recommend doubling up layers and either wearing a second set of these or getting a heavier layer to wear over them. Overall, this was a great buy and a much cheaper option than other base layers. I would definitely purchase this one again! -Piper's boyfriend :-)

[6'3" 300lbs] (2-3x shirts - 40/31 jeans) 3x/4x/5x review must read
Great for cold temps! Extremely comfortable and warm! Cannot beat the price! I have 5-6 different brands and styles, these are my favorite! Sizes defintely run on the small side. I'm a 40 waist and 2x shirts/hoodies fit me well but only if they are long enough. I'm 6'3". 300lbs. 40/31 for jeans. 2-3x shirts. All my underwear/thermals are 2x. I read reviews of being sized small so i decided to start at a 5x. Top fit looseish (you want a snug fit) and went down to my knees. Was able to pull bottoms up to my chest and still needed to go higher. So bottoms are no go but i liked how long the shirt was and it was comfortable. Working all day. Might as well ne called yoga for the positions i have to work in on a daily basis. Shirt stayed tucked in from getting dressed that morning til getting undressed that night. Never once had to retuck. Which is awesome. I bought a 4x. Top was.a nice fit and still very long. Exactly what i wanted except i wouldn't mind it being a little tighter. Bottoms were wearable but still a little loose and a little too long. Ordered a 3x. Top was tight and short. Lenth difference betweem 3x.and 4x is like 5-6" so the 3x top was too short and too tight. Kept pulling up and wouldn't stay tucked in at all. 3x Bottoms were good tight until the waist and there wasn't much stretch left but i liked the fit. For me, best combo would be a 4x top and 3x bottom. But they don't sell them like that so I'm going to order 4x from now on. Still my favorite, warmest, most comfortable long underwear I've ever had!

entry level thermal wear, as far as warmth goes.
True to size. I wear a large, and both the top and bottom fit well. Snug but plenty of stretch left, at 6'2" and 215 pounds. These are not super thick. I would place them at the entry level for thermal wear, but they do add a layer of warmth. I would find a thicker kind if you're generally cold.

Actually lives up to the ad!
Nice and warm, actually fits, and has a pee flap! Nice soft material very comfortable.

Top and bottom are same size
Unfortunately the pack comes as one size. I needed a medium bottom and a large top. The top is tight but the bottom is fine. I kept them but probably wonโt wear the shirt

Excellent, inexpensive base layer set. Ideal fit, texture and warmth
This is an excellent, very inexpensive base layer. I purchased one set, and was so impressed I purchased three more. I will likely purchase a couple more (they are very inexpensive) so I can wear one base layer set every workday during the colder months.
