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.

Not sure what size or fit type you need?

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.

Anti-Microbial

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+.

Renewable

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.

Great shirt, although neck a little loose

This is my third expedition weight piece (see my review of the crew neck, which I love), and it's great. Really like the long sleeves with thumb-holes - great for people like me with long arms (35"). My one complaint is that the neck is so loose - as you can see on the model. I have a 17" neck and the large is at least 2" too big around for me

We're glad you like the Expedition pieces! Thumb holes are a must have for long sleeves in the winter!

What a surprise

The thickness was amazing yet it fit without binding under my outer layers. Fit was just what I wanted not baggy or too tight. Cuffs were snug but not constrictive.
They will get the first cold weather workout from the end of November through December.I am confident they will pass the test.

Mike!
Thank you for taking the time to leave us a review! The Kobuk 1/4 Zip 100% Merino Wool is going to be a great insulator in the cold months!
Stay warm!

The Expedition Kobuk is a fantastic cold weather garment..can be used as a base layer or mid-layer insulating piece..soft and very warm..a formidable weapon against the cold...

I'm so glad you like the Expedition Kobuk! It's a great piece of clothing that can be used for a variety of purposes and the 1/4 zip comes in handy when you need to cool down a bit but can't take off any layers. Thanks for the review!

Best and most cost effective Merino on the market

I love Minus 33, have been wearing their items for over ten years, and some of them I am still wearing, after ten years. Very responsive company, fast shipping and they stand behind their products, which are ethically manufactured.

Mark,

Thank you for the great review and keep warm!
