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?

Honestly not a fan

Honestly not a fan. I hate the seam that goes up the middle of your rear. It makes the waistband sit lower in the back than front and just feels so off and weird (like they are sliding off your bum). I prefer my Icebreaker way more than these. Thought it was worth giving them a try though.

Thank you for taking the time to share your feedback with us! We are truly sorry to hear that the Microweight Women's Wool Boyshorts didn't meet your expectations regarding the center back seam and fit compared to your Icebreaker pair.

Your detailed comments are incredibly valuable to us, and we have shared your request directly with our product development team to review as we design and update future styles.

We appreciate you giving Minus33 a try, and thank you again for your feedback!

My favorite underwear! Love how the merino feels on my skin. Very comfortable and fabric doesn’t get smelly like synthetics. Wish I could only wear those.

Hi there! We're so happy to hear you love the Woolverino Boyshorts. It's great that they keep you comfortable and odor-free. Thanks for sharing your enthusiasm!

I bought these for my daughter. She has told me several times that she absolutely loves them. I was concerned that they might be too big. She is about a 6. 5’11 and 125 lbs. Thankfully, the mediums were perfect. Thank you!

Softest underwear

I have never worn a more softer pair of underwear. It was like wearing nothing. I ran in the boy short in rain, snow and also at the gym on the treadmill. Never even felt them ride up or move at all. The fit is perfect. The feel of the wool is the softest ever . Can't wait to order more . Highly recommend fir any runner . 5 plus STARS 🤩

Magical!

I think this underwear might be magical. I commercial fish in Alaska, which involves long, active days in variable temperatures. Throughout the fishing season, they’re comfortable, durable, and somehow blessedly odorless even when we can’t get back to town to do laundry for a few weeks (gross, I know. But less gross thanks to Minus33!).

Avery,

Thank you for taking the time to leave a review for our Micro Weight Woolverino Women's Wool Boyshorts. We are thrilled to hear that you find them to be magical! We take great pride in creating comfortable and durable products, and it's wonderful to know that they have served you well during your long and active fishing days in Alaska.

We understand the challenges of being in variable temperatures and not having access to laundry facilities for extended periods of time. That's why we use high-quality wool that is naturally odor-resistant, keeping you feeling fresh and comfortable throughout your adventures.

Thank you for choosing Minus33 and we hope to continue providing you with magical products for your future journeys.

Best,

Leg length too short for me

These are my first pair of wool underwear but I prefer the bike shorts style as this style rolls up into the thigh crease which I am looking to avoid.

Hi,

Thank you for taking the time to leave a review for our Micro Weight Women's Wool Boyshorts. We're sorry to hear that the leg length was too short for you. We understand that everyone has different preferences when it comes to underwear styles. We hope you will find other products to your liking in the future.

Love these!

I bought two pairs and they are extremely comfortable. I wouldn’t wear them under a dress, but under shorts or pants, they are extremely lightweight and breathable. I wear them when I fly. I found that they fit true to size

Not for me

I loved everything about these noy shorts except for the seam running down the back. It ended up as a wedgie between my butt cheeks. I do have s rounded, muscular butt do that may be my problem. I imagine thong wearers wouldn't even notice it. I never get wedgies with my microfiber briefs. Really wanted these to work for a trip this spring.

Hey Karen,
Thank you for taking the time to leave us a review. We are still a small company and growing so, getting feedback from our customers is very important at this stage. We will get this over to our product development team for you. Please let us know if we can get a return or exchange arranged for you.

I'm in Love with these!! They have a nice, flat comfortable waistband and the fabric is So Thin and Airy! I Live in These for any activity that will be active and sweaty🙌

I would order down a size. The ones I ordered per the size chart are nice with baggier pants, but for anything fitted, I like the snugger fit👌

Hello! I love everything about these wool underwear except for the seam up the back which I keep feeling and adjusting as I wear them.
Do you make them without the seam in the back? If so, I'll buy them all!
Please advise!

Aidan,
Thank you so much for reaching out. At this time, the boyshorts all have a seam. I am going to pass on your suggestion to our product development team. In the meantime, our micro weight bikini briefs do not have a seam in the back!
