Women's Base Layer Reviews

Take it from our customers.

"Really loving this shirt! I've worn it to the ski hill, to workouts, and for just everyday wear. It's so comfortable, and I love the color (wine). I've put it to the smell test because I've only washed it once so far. I'm so pleased with my purchase and have already picked out the next item I want to buy once it's in stock again!!"

Jill R.

Aspect Midweight Crew 1/4 Zip

"These are the softest, warmest layer of undergarments I have ever experienced!"

Martha E.

Inversion Heavyweight Bottom

"This is my favorite shirt. I love it so much, that I bought two more in different colors. They are soft, warm and cute. Feels like a second skin."

Rachel L.

Aspect Midweight Crew

"Love these! Wear them constantly for cold ski days and I forget I'm wearing them. The waist band is super comfortable and sits under jacket and snow pants layers perfectly. Would recommend for your everything long underwear!"

Sarah B.

Inversion Heavyweight Bottom

"I love this top! It’s comfortable (soft) and light weight but warm and the high neck is nice for skiing to protect from cold wind! It has a flattering fit too!"
