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.

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.

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.

Very comfortable, but didn't last long

Love the fit and the length, especially in the winter months. Like other wool products, they don't stink when out in the field for days on end and can be cleaned and dried relatively quickly.

That said, my oldest pair are almost 2 years old and have worn completely through along the bottom seam. I thought the fabric blend would make them last longer. I don't think anybody has figured out how to make wool underwear that lasts, which is a bit disappointing for the price, but not unique to Minus33.

ALL SEASON COMFORT

I live in Minnesota, winters are cold and long. Summers are hot and moist. Since I discovered these boxer briefs a few years ago, they have been my GO TO undergarments for all seasons. I have tried other merino underwear (Icebreaker, Duckworth, Smartwool) and these are by far the most durable and comfortable. 5 stars all day long.

Mark,

We are happy to hear that our Minus33 boxer briefs are your 'go to' undergarment for all seasons. Thank you for this awsome review!

Great for hunting

I bought two pair for September elk hunting when it's hot. All the great merino-isms (don't smell, comfy, etc) but have been more resilient than standard merino boxers regarding wear and tear.
