  • Seriously warm and comfortable without bulk.
Size: XX-Large Color: Black
These are warm and comfortable without adding the bulk of traditional, cotton thermals that also shrink up. They’re so lightweight that you forget you have them on, except that you stay warm with these close-fitting thermals. I was advised to buy a size up, but I didn’t, and they’re fine. I also was hesitant to buy a top and bottom set, same size, because I usually don’t wear the same size top and bottom, but I bought my top size, XXL, and that worked fine for bottoms too because these are so form-fitting. Laundering? I hang-dry mine. I’ll likely buy another set. They’re great! ... show more

  • So soft and comfortable
Size: X-Small Color: Navy
My son is 11, 4'10", 92lbs, and depending on the company fits youth large, youth XL, or now recently, men's XS. These are perfect for him. The sleeves, leg, and torso are slightly long but not too long, and good to maintain coverage when he bends/sits. The fabric is super soft and stretchy. I've only washed it once and it's been worn once, but very happy with this. ... show more

  • Excellent for Marching Band
Size: Large Color: Charcoal
I got these as base layers for my son's marching band season. They were perfect. Not too thick, he didn't overheat, and they kept him warm under his uniform. They also have a ton of colors, so great for whatever shade your band wears. Under 35 degrees, you're still gonna want a coat for the rest of the day, but they'll get you through the halftime show with just the uniform, even if it's frigid! ... show more

  • They get stanky quick
Size: Medium Color: Black
They fit super well and are definitely warm. If you're okay with having to wash them after every use then buy em! I can't complain too much though... I use them for hunting where I am literally sitting still for hours and not sweating a drop but they still get stanky - and yes - I do shower! They do what they're intended to do though, they keep you warm! ... show more

  • Sizing is a bit silly
Size: Medium Color: Charcoal
Really love the comfort of these. They are very form fitting. The only issue is, the bottoms are for someone with a 41” inseam. I usually wear 32x34 pants and, as you can see from the pic, these are a bit long. I suppose it’s extra material for your upper body but I don’t really want that. I wish they would separate them so one could order the top and bottom separately. Other than the sizing, they are the warmest, most comfortable thermals I have ever worn. Other than the silly length, I’m happy with my purchase. Probably going to order another set in extra small and see if those bottoms would fit. I’m 6’0” 170 lbs ... show more

  • Fits well, keeps you warm
Size: 4X-Large Color: Black
I recently bought the top and bottom set because I frequently work outdoors, and needed some layer warmth. I am a large man, 6'3" approximately 340lbs, and the 4xl fits great. Is not too tight, which allows some breathability, but snug enough to really add a nice base layer of warmth. Would recommend! ... show more

  • One of the better thermals out there
Size: Large Color: Black
I've been looking for good thermals for years most are either too thick or made of material that can't be worn for too long or too short.. this one was good on all fronts. One of the better ones definitely will buy another one.

  • Effective and comfortable
Size: Large Color: Black
Very comfortable, and accurate size cratered to your size! I am a security officer who works at night, and I can gladly say these are the real deal. It sticks to your body but not so much to where it's uncomfortable. Would buy again.
