        Why Merino Wool?

        Moisture Wicking

        Minus33 Merino Wool regulates the amount of moisture on your skin by absorbing any moisture or sweat on your body. Then, the absorbed moisture evaporates out of the fabric into the atmosphere.


        Merino Wool fibers naturally reject any bacteria in moisture or sweat as it is wicked away, so foot fungus and smelly odor will not be a problem while wearing our products.

        Insulates When Wet

        Wool will absorb up to 30% of its weight in moisture without feeling wet or clammy. If you do get wet, wool will insulate you better than cotton or polyester materials.

        Fire Resistant

        Merino Wool insulates against high temperatures and does not readily catch fire. If it does, it self-extinguishes. When Merino burns, it doesn’t melt and stick to the skin like synthetic fabrics do.

        UV Protection

        Don’t worry about sunburn on a sunny day summiting a peak. Lightweight layers have a UPF rating of 25. Midweight and Expedition have a UPF rating of 50+.


        Merino Wool has a low environmental footprint and naturally returns to the elements. Shear a merino sheep in the morning, and in the afternoon they’re happily nibbling their way towards renewing next season’s clip.

        lovely product

        I found the medium in the light weight to be small compared to the medium i purchased last spring in the mid weight.

        Sorry it didn't fit quite right. If you would like to exchange it please reach out to us. Thank you for your review.

        lightweight warmth

        I love how light weight this 1/4 zip is. The heavier weight ones tend to be a bit tighter and feel somewhat constricting (which is fine when you are really cold), but this weight is great to have to throw on for a bit of warmth or even to wear as your shirt of over a cami.

        Glad you like it. Thank you for taking the time to leave a review.

        Good, but short not as good as the other products

        The shirt is comfortable and I wore it Nordic skiing as well as around the house a couple times. I received the lightweight xs crew neck shirt for Christmas and wanted this 1/4 zip for skiing. It is hard to describe why, but immediately upon receiving this shirt it seemed different as if from a completely different, but similar producer. I assumed this shirt would be similar to the crew, but it is shorter than the other shirts. For example, I am wearing high waist jeans and this top rolled up above the jeans. The arms are good length, maybe a bit long, which is normal since I am actually a petite size.


        Thank you for taking the time to write this review. We apologize for any disappointment that you may have with the fit of your Minus33 Liberty 1/4 Zip. We have a new fit coming out in the summer of 2022 that may suit you better.

        High quality, almost perfect

        This is a really nice layering piece. Comparable or better than any other brands I have tried.

        However, I found it sized small compared to my midweight tunic, which would be OK since I wanted to wear it as a base layer. But I ultimately returned it because it is not as long as my midweight crew.

        I really enjoy a top that stays tucked in, covers my bum, and doesn't expose skin when I raise my arms

        Customer service was exceptional & I look forward to comparing the length of this one to other light or micro weight tops

        Love this shirt!

        This shirt fits great, feels awesome and keeps me warm even though it is lightweight. I got the red. The cut and seams are very well done. I’ll be ordering this in other colors, Please make more! Cobalt blue would be nice :) I’m 5’3” 145 lbs and the large fits perfect.
