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 certified PFAS-free 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.

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.

Small coverage

Love the material, but they are not a full coverage. They ride up extremely bad. So wearing them with my EMS pants I just have a weggy the entire time!

Sorry you were not completely satisfied with your Woolverino Bikini Brief. The boy short may be a better option for you. Thank you for your review.

Best underwear!

I was skeptical, but decided to try a pair (price is a bit steep)...best decision ever. M size fits like it was made for me, and I feel SO comfortable wearing it, not to mention warm...and I love the fact that it does not smell, either...I am probably going to get another pair- just wondering if any other colors will ever be available? Thanks for making such a great product!

I like 'em. Need to get more.

Soft, light material that helps keep you from overheating down there. The only thing that would make them better is if they had less coverage in the back, kind of like the cheeky style. I'm not a fan of the full coverage in the back, but that's just personal preference. Other than that, these are one of my favorites.

Thank you for sharing your experiences so far! We're glad you're loving them!

I Purchased These…

I Purchased These For My Wife And So Far She Loves Them. The Sizing Was True For Her. They Are Soft And Comfortable And Great For Warm Or Cold Temperatures. She Normally Doesn't Like Large Bands On Underwear But Found That For These It Wasn't A Big Issue As It's Very Flexible And Not Overly Thick So Not Really A Negative But A Note For Anyone Looking At These.
