I ordered these for my son who lives in a RV. He loves their warmth and comfort. If you are familiar with Massachusetts winters, you can realize how freezing and below freezing the temperature can be. I thank you for your kindness and assistance you showed me as I was placing my order on behalf of my son. Regards, Catherine Love

Super warm and so soft and comfy

Feels great and looks great. Sized as expected from the size chart.

Best underwear all around

David archy underwear are the only underwear I buy. I’m very picky about my underwear and have searched for years! I’ve worn david archy for over 4 years now and they have satisfied every need and preference.


I already have David Archy underwear and they are amazing! I decided to purchase the xl thermal underwear and I have to say that I am NOT disappointed! The fabric is so soft and feels great against your skin. The material keeps your body super warm even though it's not thick like sweatpants. They have managed to combine excellent materials with a design that compliments each other perfectly. If you're looking for a high quality set that will keep you warm and looking good, I fully recommend purchasing this set!

COTTON version is GREAT Quality, Soft, Warm, Comfy

BEWARE: Looks like the manufacturer is transitioning to acrylic. My review is for cotton. Acrylic will probably not be as nice. If you pick a different color, you may get a different fabric. The acrylic product should not be able to benefit from reviews citing the wonderful cotton fabric. I'm returning the acrylic pair I bought by mistake.

These are the highest quality clothing items I've purchased in years. The fabric is soft and feels luxurious. Nice thickness--thick enough to be warm, but it doesn't feel like you're buried alive in fabric. Often you pay more for quality, but just get pricey junk, but these are worth the price. I'm going to be living in these all winter. Great for working out, too. Sure the tech fabrics wick well, but cotton just feels better.

These might be tad thick if you're wearing them under tight pants, but I think it's worth it because thin polyester thermals are gross and not that warm.

I bought two sets of these: small and medium. I'm a man-shaped woman with a 30-inch waist (130 lbs). The small is just slightly tight in the waist and the legs are a little snug, but still wearable. The medium fits well. Length is good for my 32-inch inseam.
