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?

Core Spun Technology

Core Spun yarn provides extra durability while still offering merino's properties next to the skin. The nylon inner core is wrapped with Merino Wool and a touch of spandex for stretch.

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.

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 these. I have been looking for some all merino boxers or the majority of the fabric merino. Very happy with these. I do wish the waistband was a little bit wider for more comfort.

Finally, women’s boxers that are long enough, light weight and comfortable!! I wear them under my gravel bike shorts and pants and they are perfect for multi-day outings. Will also use them hiking and cross country skiing. Looked a long time before I found these - they’re great! Will buy again.

the best women's boxers

I've been looking for women's boxer shorts and am so glad I found these. They are so soft and comfortable both under clothes and for lounging/sleeping. Great for wearing with skirts/dresses for a little extra coverage/to prevent chub rub. I'll definitely be getting additional pairs so I can wear them more often.

great for mtb

I wear these under my baggy/durable mountain bike shorts. They're perfect! Lightweight and just the right length. I'm thinking they'll be good under hiking pants, too. True to size (purchased S). Please keep making these!
