"warm but was honestly expecting them to be warmer for some reason. im in lift operations so im outside for most of the day and while these do keep me pretty warm i have other pairs that do a better job for less money. the ankles i wish were more fitted and kinda bunch up in my shoes regardless of if i put my socks over or under them. overall pretty good though."
"These are lightweight and warm, easy to move in, everything you want in a base layer"
"not gonna blow your mind but decent enough, comfortable and lightweight"
"Thin but warm! I like them!"
"They provided exactly what was required of them - warmth and comfort on my trek through the Himalayas."
"This is my first pair of the coefficients, I am a regular wearer of the merino 150’’s. So far they are comfortable and effective. I’m hoping to get a little longer life span out of them than the merino, which can wear thin after a long season of use."
"These are way warmer than I expected. They also seem to be great moisture wickers."

"Glad to have pants back again. . . these are perfect for adding over the base layer on those cold weather tours keeping just a bit warmer for safety margin and still dry out fast. Would still like to have the regular thickness version back (perfect add for cold weather lift served), but my old ones are still holding on!"
"Along with the mid-layer top, these pants provide excellent warmth for their weight."
