Fit FAQs

What if I am between sizes?

If you are between sizes, we recommend sizing up or down based on what fit type you would prefer, and based on how you plan to wear the piece. Our knitted merino is stretchy and you could realistically go with either size. If you would prefer an Athletic fit, size down. If you prefer a Regular or Relaxed fit, size up.

Do I need to size up/down to layer?

Generally, no, you do not need to purchase a different size than normal. Our base layers are designed to fit right into your current layering system. They are also designed to work with other products in our line, too. You may wish to adjust your sizing if you plan to wear one of our garments in a way that it is not intended, if that's the case please feel free to contact our customer service team for help.

Does your clothing run true to size?

Yes, our clothing runs true to size and is sized similar to most other American brands. If a sizing discrepancy is discovered, you will see fit advice in that product's specific listing.

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+.

Australian merino wool sheep


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. 



Total Easy Care (TEC) Merino apparel is designed for today's busy lifestyle. Total Easy Care Merino garments are all machine-washable, and are suitable for tumble drying.

Even after frequent laundering they retain an 'as new' appearance. They won't shrink, lose their shape, fade or color-bleed. They remain soft and comfortable for the life of the garment.

Customer Reviews

Based on 9 reviews
Great all-around top

Finally, a 100% merino wool top for women that is long enough to cover my belly! It is not nearly so long on me as it is on the models, but it does come a couple of inches below my hip bones (I'm 5'10"). The material is thick enough that my bra doesn't show through. This top is light enough to wear on summer days and I think it'll be great for layering this winter. This washes easily and dries fast. My only wish is that they had this with a v or scoop neckline. I'm not fond of crew necklines.

If you are looking for a V-neck we do have a micro weight Woolverino blend T-shirt. That shirt is 84% Merino Wool, 12% Nylon & 4% Spandex. This top is so comfortable & cool in the summer and great for layering in the winter. Thank you for your review.

Changing my opinion of wool

I was reluctant to buy wool short sleeve shirts for an upcoming hiking trip--but they could be a new go-to. They are soft, not at all itchy as I'd feared and to have wool that can be washed AND dried--game-changer for me. Hoping for more colors to choose from in the future. The fit is true & comfortable.

verdict is out

Minus 33 was recommended to me. I was very happy with the two base layers. The were very comfortable and worked well on my morning walks. However, at the first wash of one, it snagged and developed a hole. I tried calling but was refered to the website for returns. It has been returned and a replacement is on its way. I live in the north of Fanconia notch and look forward to making a trip to your store. Thanks for asking.


Thank you for taking the time to leave a review. We're glad to hear that you were happy with the comfort and performance of our Minus 33 base layers. We apologize for the snag and hole that occurred during washing and are happy to hear that a replacement is on its way to you. We always strive to provide high-quality products, so we appreciate you bringing this issue to our attention. We look forward to welcoming you to our store in Franconia notch and hope you continue to enjoy our products. Thank you for choosing our brand.

Love this

I got this in the gray and found it to be very nice weight, softness and quality and fit. So, I ordered one in black. Same features as the gray but the black one is a bit smaller and a bit too snug at my current weight. Not sure if this is just a fluke.

Good morning!
Every so often a piece just doesn't fit like it should. We are happy to get you an exchange for another one to help with the fit! Thank you for taking the time to leave us a review and still leaving us 5 stars!

More colors please!

I love these shirts. I’ve used them for layering in European winter weather and by themselves in a warmer northwest fall. They have a flattering fit. I just need more colors.


We're happy to hear that you like our shirts and that they fit well. We hope you'll continue to find our products useful and that we can help you find the perfect shirt for your needs. Thanks for the feedback! We will pass your suggestion along to our product development team.
