  • Fit and function as described!!
Team Name: C-Black&Army Green Size: X-Large
As other reviews mention, they go the extra step with packaging. Nice outer box and each set is packaged in a zip lock style bag. My husband's comments below... The feel and fit is perfect. They are fitted, so I was happy I went a size larger than I needed. I lost the slim and trim figure after 50...Ha! The sleeves extend over the wrist, allowing more retention of body heat. Also, the neck is somewhat loose but fitted at the same time. I dislike shirts that ride too high, too low or tight around the neck. Waistband elastic fits the same, not too tight or loose. With the first test fit you can tell they help retain body heat, and have the moisture wicking feel of higher end brands. I see these becoming a frequent choice to wear this winter. Would definitely purchase again! ... show more

  • This is the thermal-wear you need
Team Name: T-Black&Black Size: X-Large
Waist size 36/38, you’re going to want XL. I did pick the right size and will say, keeps me warm enough. Lightweight enough, unlike the traditional flannel material. This product is absolutely worth every penny. I personally don’t care about the look, I’ll be wearing it underneath my actual clothes, but it’s just big enough for a little breathing room, while still being quite snug. ... show more

  • Absolutely ROCK SOLID product
Team Name: C-Black&Black Size: XX-Large
OMG these are absolutely amazing beyond words. I expected lightweight microfiber lined kinda good sorta thermal underwear kinda. What arrived is these absolutely amazing Romison thermal underwear and they weight a ton and feel like a million bucks. I am totally shocked how good these are. Edit: Well it's been a couple of weeks and I can't believe how good this product is. Truly amazing. ... show more

  • Warm and 9/10 fit
Team Name: C-Black&Black Size: Large
I say 4.5. I wear large shirts and medium shorts. I have a 30" inseam. I bought large, and the tops of these fit great, a great balance of comfort and skin-hugging fit. The bottoms are tall in the crotch, which is great because I hate the pants that have too small of a but bucket. The are loose around the legs, especially the lower legs, which makes getting socks on more difficult (I tuck the long underwear into my socks). That is the fit opinion. The warmth opinion is 5 stars. they are a great fabric, not catching dry skin, and keep me warm. ... show more

  • Great product
Team Name: O-Black&Grey Size: X-Large
The product is as described and acceptable quality and durability. I have bought 4 or 5 sets over the past 3-4 years, some as gifts for my son. They'll last a couple years, even with frequent use. They're not bulky. Let me bring your attention to the 2nd picture the seller posted - which states: 72 hour warmth - I don't want that to mislead anyone... these do not run on battery or anything like that. The warmth actually lasts much longer than that - seller perhaps confused with multiple products or just plain inept. The warmth lasts as long as you produce body heat via respiration; I promise! ... show more
