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

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.

Great shirts

Ordered several colors. Besides all the great properties Merino wool has, I love that these also can be dressed up or down, they are easy care, hems stay in shape, and they come in lots of colors. Highly recommend!

Hi there! Thank you so much for taking the time to leave us a review. We truly appreciate your support and are happy to hear that you love our Midweight - Ossipee Women's Crew 100% Merino Wool shirts. It's great to know that you find they can be dressed up or down, and are easy to care for. Thank you for the stellar recommendation, and we are thrilled to have you as one of our customers.

Warm and great for temperature regulation. Also long enough for tall people

This shirt is very well made and it's got nice long sleeves and a long enough trunk that there's no problem reaching up and having the shirt ride up. I bought this for a cruise to Alaska, because I'm out on the deck rain or shine. I'm sure it will work wonderfully for that, but what I've discovered, is this top and the matching pants are also my favorite pajamas! I always thought of base layers as something only for colder weather, but this set helps me regulate my temperature even when I'm inside. I had some health issues last year that put me into overnight menopause, and while I'm miserable in cotton (esp at night), paradoxically, I'm able to stay cool and also stay warm in this top without sweating. This was such an unexpected bonus that I'm going to slowly move my wardrobe over from cotton to wool as I replace pieces.

Natasha,

Thank you for taking the time to leave a review on our Midweight - Ossipee Women's Crew. We are thrilled to hear that the shirt has exceeded your expectations and has been useful for both outdoor activities and as pajamas.

We take pride in the quality and design of our products, and we are glad that you have found the long sleeves and trunk length to be comfortable for tall individuals. It's great to know that our merino wool has helped regulate your temperature and provided you with a comfortable experience even during overnight menopause.

We hope that you continue to enjoy your Ossipee Crew and matching pants. Thank you for choosing our brand and for your support. We look forward to serving you again in the future.

Best regards,

The Minus33 Team

Perfect

Bought this for an upcoming trip (hiking) in Norway. The princess cut just skims the body, making it a great 1st layer. I usually wear a M or L, and decided on the M. Glad I did. It fits perfectly. Very soft and warm. Can’t wait to wear it.

Hi Cjaws.
Thank you for your review! We are thrilled to hear that our Midweight - Ossipee Women's Crew worked well for your upcoming hiking trip in Norway. We are glad that you found the princess cut to be a great first layer and that the size M fit perfectly. Our 100% Merino wool is known for its softness and warmth, and we are happy that you are looking forward to wearing it. Happy hiking!
Best,
