    • Lightweight, comfortable, warm.
Team Name: Regular Waistband Size: Large Color: Charcoal
Product arrived promptly. These are what I would describe at light/middle weight long johns. There are well made, very comfortable, and a good underlayer, with appropriate over layers. These are not nearly as warm as, say, Merino wool blends, but are priced well for what they offer. I started with a pair of bottoms, and like them well enough that I'm getting a full set. Rating 5 stars for overall value, and quality. ... show more

    • Good product, good price just watch your sizing
Team Name: Regular Waistband Size: Large Color: Black
At this price point, I think they're as good as you get. Warm, stretch and comfortable. Only issue I have is sizing tends to be smaller than I expect. At 6'3", large inseam is a bit short although waist was comfortable.

    • Great Fit, Quality Fabric that Feels High Tech
Team Name: Regular Waistband Size: Large Color: Black

I'm about 5'8", 185 lbs. I wear a size 36-38 waist (closer to 38). I ordered a size Large. These thermal underwear have a "high tech" feel to them, they make me feel like an astronaut with access to premium space-age fabric. I say this because of how flexible the fabric seems to be, it kind of adjusts itself, molds itself, to my body. It fits me perfect at the waist, yet when I tug on the waistband, it easily stretches to where I think that I can probably gain 25-30 pounds and still be able to comfortable wear these leggings. Length-wise, the ankle bottom part has this same elastic trait, to where I think that somebody a few inches taller than me would fit into these leggings just fine. The stitching is uniform and looks strong, and they come with a printed on tag, which is convenient and eliminates discomfort or having to remove it yourself. The crotch area of the pants has reinforced stitching. See photos. These underwear seem like they will withstand accidental wear/use just fine. For example, I don't have to be worried about easily ripping them due to stretching too much, or snagging them on a cabinet knob. Despite the size/fitting guide suggesting that I order XL-2XL, Large fit me just fine with plenty of room to grow. I would recommend somebody up to about 5'10", 200lbs to go with the large, however, due so at your own discretion. Finally, referencing my uploaded photos, the sun was hitting these leggings, making them seem like they are lighter in color than they actually are. Have no fear, these leggins are jet black as advertised. ... show more

    • Love these things!
Team Name: Regular Waistband Size: Large Color: Black
I was never a thermal underwear guy before, but I am now in a living situation where I often need to wear "real pants" (re: not sweatpants) in an area where it's regularly freezing temperatures during the day. With this in mind, I regularly wear these (I own a few of this same one) daily and I love them! They're extremely comfortable, like wearing pajamas all the time, and they definitely add an extra layer of warmth when the wind is biting and you're wearing thinner work pants. Can't recommend them enough, honestly. ... show more

    • Well-made and warm.
Team Name: Branded Waistband Size: Small Color: Charcoal
Product serves it's purpose, both warm and tight-fitting, so that warm-ups, trousers can be worn over them.

    • Very warm and comfortable
These thermals are amazing. The fit is really good. They fit a little big but don’t bunch up to bad. Love the fleece lining. Very affordable.

    • Good for the price
Team Name: Regular Waistband Size: Medium Color: Navy
Material is already "pilling" after a few wears but incredibly soft and warm. Just get a fabric comb.
