Making clothing can be a dirty business, but we strive to keep it clean. Our line is crafted for quality and long-term performance. And we limit what we make: small-batch production ensures every garment is built to the highest standards and finds a loving home. Our approach minimizes landfill waste and uses less energy and water. We know it’s disappointing when a style you love is out of stock, but we appreciate your joining us in our pursuit of the highest environmental standards and carbon neutral impact.

— Alexander T. (5/5)

Woolies pro tech is nice

"This is a lightweight base layer that is very warm , comfortable and looks good. I’m 6’3”, 195 lbs and size Large fits well with plenty of length in body and sleeves which is always an issue for me"

— Eric M. (5/5)

He loves it

"A gift for a friend and he loves it - he he’s worn it several days in a row, washing in between and it dries quickly. Great quality and cut. He’s getting compliments"

— Deborah S. (5/5)

Replacing the one I bought in 2010

"The moths got to it before it wore out. My favorite piece of clothing, I think, and it’s been with me from the jungles of Burma to the glaciers of Iceland. Great product."

— PHILIP S. (5/5)

Very warm soft and comfortable

"This is an excellent fitting, very warm and soft top. I found this very comfortable to wear over a T-Shirt in 7° C weather"

— Richard L. (5/5)

Great skintight baselayer

"Really nice baselayer to wear under anything for almost anything. Love to wear this when exercising as my first layer, but especially like it with short traveling trips. Can wear it all day at airport and on plane to stay warm with the AC and it's still thin enough to keep wearing it while being outside during a warm/hot summer day."

— Simon G. (5/5)

incredibly soft and comfortable, i worry a bit about durability

"Beautiful color and an incredibly soft and comfortable fabric. It doesn’t have the feel of durability like I have in some of my Marino pieces, and certainly some from ibex. Time will tell on that though."

— Alan B. (4/5)

Thumbs up

"My husband loves the material, fit and feel of this pro tech 1/4 zip top."

— Suki M. (5/5)

Pro Tech base layer series

"The Pro Tech series is for warmer fall and spring conditions. for deep winter I run the IBEX 250 for long Jan/Feb backcountry trips. Quality gear for a comfortable day above 10,5 YEAH!"

— Mike P. (5/5)

Super thin

"I thought I was buying a base layer that would be a little more thicker than what I received. You referre to it as a Woolies there is nothing what so ever woolie about it except the fact that it is made out of wool. This was very misleading. Do you have a product that is a little thicker? Please let me know. I gave it a 5 star because I know it is a good product just mislead???"

— Lee W. (5/5)
