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+.

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.

LOVE this undershirt!

This fabulous undershirt is well made with thick, soft material. I wear it almost every day and never am sweaty or clammy in it - wool is wonderful! Definitely designed for a woman's curvy body, I appreciate it is body hugging, but not tight, and easy to move even with layers over it. Well worth the price as it is a long term investment and made to last!!

Thank you so much for taking the time to write a review for us! The 100% Merino Wool Tanana Women's Crew - Expedition is a great piece to have during these cold months!

Year Round Comfort

I've been wearing Minus 33 long and short sleeved t-shirts for years and in all the different weights. I find them to be my go-to choice winter, spring, summer and fall. They're easy to take care of, soft and itch free in all temperatures. I live at 9000 ft. elevation so it (almost) never gets above 80 degrees.

Hi Priscilla,

Thank you for taking the time to write us a fantastic review. It's great to hear that you are a long time customer of Minus33! Also, that you've been enjoying the quality and performance of your Minus33 garments in those higher elevations where you live! Thanks again for the great review.

Stay Warm,

-Steven D

Great for cross country skiing!

Bought heavy wt top mid weight bottoms. Been out in single digits numbers and they are great. Also bought the glove liners which are great as well
I'm 5 ft 2 1/2" wt 128 lbs. Medium is slightly long but comfortable for me.
Wish you had merino wool mitten for a liner.
Delivery was quick. I have a feeling this company cares.


Thank you for your review! We will pass your suggestion along to our product development team, for the merino wool mitten liner. We do care, and we stand behind our products! Thank you!

Fabulously Warm

I love my Minus 33 expedition tops and bottoms and have never been warmer in the winter months. They are soft and wash well and because of that I now have multiple sets.


We are glad to hear that you are staying warm wearing your Minus33 Tanana Crew. Thank you for the fabulous review!
