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.

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+.

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.

My measurements are 39-34-42.
The fabric is really soft and surprisingly sturdy for being lightweight. According to the size chart I’m between L and XL so I went with the XL. The XL fits great everywhere except for the hips. It’s very, very snug at the hips. If a 2XL size was offered I fear it would be too large at the chest and shoulders. I’ve placed several orders here and I’ve noticed the clothes tend to be best for tall and skinny folks.

Thank you for your review. If you decide you would like to try a larger size and it does not work out for you, our returns process is real easy.

Mom’s favorite.

Purchased first one for mom to replace the thirty plus year old top like it that she was clutching. She liked the new one from M33 so much I got her another one. Something tells me this would be a bigger hit with women if it was offered in a few more colors. It’s definitely a winner according to mom.


Thank you for the fantastic review! We are happy to hear that your mom is loving her Minus33 Lafayette Women's Lightweight Tank Tops. We will pass along your suggestions for more colors in this item to our design team!

Just what I needed

Although I live in the 1/4 zip wool shirts - there are days when I don’t want a heavy vest or sweater on top but I need a little more. The Tank Top is just perfect for an undergarment that helps regulate my body temp! I love it!!


Thank you for the great review!

Not disappointed

Once again, you have knocked it out of the park. I love the way the material feels and is just enough under clothing to provide warmth or to feel cool. I truly enjoy every piece of clothing that I have ordered from Minus33. I have also bought pieces from my children, and I’m always overly pleased with the products that I get, thank you once again and could you give more colors to us in the products that you don’t but I’m good. Thank you for providing me with something that I love


We are happy to hear that you love the way the material feels on the 100% Merino Wool Lafayette Women's Tank Top - Lightweight. Thank you for suggesting we make more colors, we will pass this recommendation along to our product development team.

Impressed with the quality and fit!

First product purchased from Minus33. It's perfect to add another layer of warmth to my core underneath my winter sweaters. Also the fit is great. Much better for me than Smartwool products which are also more expensive. I liked the tank top so much I ordered a long sleeve v neck in the medium weight and I'm thrilled with it too. I use it for a sleep shirt. I live in Montana and we like to keep the bedroom very cool. The v neck does the trick! Thank you Minus33!
