Real silk base layer
Reviewed in the United States on March 21, 2023
Size: XX-LargeColor: BlackVerified Purchase

This is silk - real silk, but it is thin. A recent test by the US government ranked fibers by warmth as animal fibers (such as fur or wool) as best, cotton next, Spandex as third, silk as fourth, and synthetics as fifth. By itself, silk is not warm. Thick silk base layers, such as Lands End silk base layer for men, are warm-ish. At best silk base layers make other clothing move without making cold gaps next to your skin. This is good enough. However, Thermasilk is best if you put something warm and close to your body over it. Then it really shines as a base. Your movement will be unrestricted and your core body will be warm. It also packs up into a really small bundle if you have to backpack it. Thermasilk is light weight, easily packed, and helpful when building layers. It also doesn't pick up odors, so it doesn't stink. Finally, you must never discount the fact that it feels like silk. On top of all that, Thermasilk offers a reasonably decent price.

Edit 2- Waistband is Comfy-ish
Reviewed in the United States on October 1, 2014
Size: Medium TallColor: BlackVerified Purchase
These were different than the ones my grandma bought me last year, and I know these are the same because I saw the comment I made on these under my grandparent's account and purchased them myself this time.

The only difference is the waist band. My number one love for these was the covered waistband, like the Hanes comfort soft or whatever it's called. These have the typical scratchy elastic waistband that is not covered with any of the fabric (silk) so the waistband is itchy. Wear your boxers either a little high, or pull your silk pants down some, forreal.

Otherwise, these are fantastic. I wear them literally everyday along with the silk shirt by this brand, and my shirt is still holding up well. Obviously you can't wash these (or any silkwear) in a machine or you'll destroy them - learned that the hard way (obviously, right?) but I hand wash mine instead with a tiny bit of detergent in the bathtub and then air-dry them and they don't stretch, shrink, or unthread themselves. I have stretch lines in the shirt, but it's a year old now and for being paper-thin silk, that's a decent buy.

This set of this brand for pants and shirt adds up to about $55.00 but has free shipping. So for a year of everyday wearing, these were more than worth it and I had to buy them again for the upcoming winter.

Silk is lightweight, like the package says "warmth protection [or quality or level, I don't know] is a 1 - which is the lowest level of warmth - so don't expect these to keep your person from freezing in really cold climates. For Michigan - and northern Kentucky that I live in now, these are the best at keeping the chill away. Moisture wicking is extraordinary with silk, too.

After wearing these, I came to find out that while the waistband is not covered, it is indeed soft and does not itch or poke. I gave back the star I initially took away. Thanks, Terramar.

WAISTBAND actually kinda bends and folds in on itself making it slightly annoying - especially since it curls around your pants or boxers.

These are the silks I was looking for.
Reviewed in the United States on November 14, 2012
Size: LargeColor: BlackVerified Purchase
I love silk because it's not too hot indoors, and keeps the wind off my legs outdoors. In winter, the wind always cuts through my pants and my knees become ice cubes. Years ago someone gave me a pair of silk underwear from LL Bean and they were wonderful. My outdoors exposure in winter is like from the parking lot, or a block or two in the cold, to get to an office. When I come inside, I don't want to have to peel off some heavy or artificial-fiber feeling leotards from under my britches. With silk, the strong edge of the cold outdoors is blocked and the silk is so thin that indoors I even forget I'm wearing it. Completely comfortable. I ordered these thermasilk pants from Amazon because of the price and they're available by Amazon Prime. They are like the old Beans, light and not too tight. My waist is 36 inches and the large fits just fine. Silk gives anyway. I hate icy wind on my legs (regular pants just don't do enough for me usually) and these silk (real silk; I was skeptical of 'thermasilk' (didn't want part polyester) but its really 100% silk. I don't care if they don't last for years. For this price, I'll pay for two pairs to get through any winter, any year. If they last for years, that's a bonus but I can take it a winter at a time. No sweat, excuse the overlaying imagery. I won't ski in these because I don't ski, and I hate artificial fabric against my skin. Yeah, they're thin, and COMFORTABLE. I haven't tried their shirt or upper body wear because I have good down jackets. Comfort feels good.Terramar Men's Thermasilk Pant
