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.

Learn About Layering

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. 

TOTAL EASY CARE

MACHINE WASH AND DRY

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.

Couldn't be happier!

I am a smokejumper with the US Forest Service and can't say enough about these boxer briefs. I've been searching for a pair of underwear that don't ride up my thigh and bunch and these stay put. Not only that, I've worn them for multiple shifts on jump fires and they don't get funky. I don't have room for extra pairs of underwear when I jump so to have a pair that feels fresh after three or four days is amazing. Worth the money and these will eventually be the only underwear I use in the future.

Sounds like these are just exactly what you needed! Glad they work out so well for you. Thank you for the review.

Best Merino Garments Available

Although I am reviewing the merino boxer underwear I want to complement Minus 33 on the quality of the other products that have been in my wardrobe for over five years. This includes turtle necks, tee shirts, toques, mid weight front zip sweater, heavy weight hoodie and socks.
I value function and quality and although I don’t see my underwear as heirlooms, some of my other merino garments will possibly outlive me.
Make sure you get the right size in the boxers and if you have any problems, I have found that the Minus 33 customer service folks are very responsive.
I wear these boxers in our Canadian winters and they have lasted me four years. That is quality.
Thanks Minus 33

Glad to hear that you are loving all of your purchases so much! Thank you for taking the time to leave a review.

The Only Underwear I BUY

I work as a firefighter in the summer and at a ski resort in the winter. All seasons, extreme temps, year round I wear Minus33. I love them.

So happy to hear that you love them! Thank you for your review.

Fit and comfort!

I bought two pair and the fit great and are comfortable. I bought The long leggings versions while back and gave them a five rating. These do not have a thick enough waist band and this slide down all day during activities.

Love Minus 33

I have quite a few different Minus 33 items, socks, underwear, shirts, and a hat, they are all fantastic. These boxes briefs feel great, are very soft and are the perfect weight for all seasons. The only thing I'd like to see is for it to be fully tagless. Otherwise they are great. All of my Minus 33 pieces are top-notch.
