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 is 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?

Comfy and Warm

Got the midweight in medium. I'm 5'4", 140lbs and normally between a S/M on bottoms. Definitely could have gone smaller. Super soft and comfy, felt like I was wearing pajamas even when I was wearing jeans. Was backcountry in temps below freezing with high winds and sleet and was more than comfortable when moving around and sleeping. I run cold and will get the heavyweight next.

Great fit and perfect for trip to Iceland

I shopped around for thermal base layer bottoms for a recent trip to Iceland. Every pair I tried was too loose in the legs and too tight in the waist. These fit perfectly, were very comfortable, and kept me nice and warm during my trip. Now that I have them, I'll wear them at home next winter too. I would just note that I would not wear these out in public without another layer over them (things were too visible...)

Thank you for taking the time to leave a review for our Midweight Women's Wool Bottom Thermal Base Layer. We are thrilled to hear that you found the fit to be great and that it was perfect for your trip to Iceland. We understand the importance of finding the right base layer for colder climates and we are glad to have met your expectations.

We also appreciate your feedback about wearing another layer over the bottoms in public. Our team will take this into consideration for future product development. We hope to continue providing you with comfortable and warm options for your winter adventures.

Thank you for choosing our product and we look forward to serving you again in the future.

Best,

The Minus33 Team

Unbelievable Quality

This wool top is of unbelievable quality. It’s amazingly soft and also quite warm. One thing would make it even better though - petite sizes. I’m 5’1” and the shoulder insets don’t fit very well. Because I’m using it as a base layer, the poor fit under the arms isn’t visible and the top is still comfortable. I’d buy it again.

I had a pair of Minus 33 years ago and recently

I had a pair of Minus 33 years ago and recently reordered. The medium weight sz sm is a perfect fit for me. I also tried the Lt weight top and found it too small/constricting for me so I exchanged it for the medium weight sz sm which fit perfectly. Great product great people.
Will order more. Love this company.

Perfect for long legs and high waist. Great material fit texture, quality, and craftsmanship. Put first pair to the test ordered a second pair because I am so happy with the extra long length and quality of garment. I will definitely be ordering from -33 again specifically for their long length pants.

Such a good investment for the cold

Suuuch a good purchase! They're soft, stretchy, and warm. I get overstimulated wearing multiple layers and this has made it much easier to weather the colder days of winter this year. Highly recommend.

Very pleased, ordering more

As someone who is 5’9”, but on the smaller size, I have struggled for much of my life to find pants that fit my entire leg. Safe to say, these pants have allowed me to wave my struggles goodbye.

While they are slightly baggier in the groin area, I don’t mind because I’m just so glad to have something that fits the length of my leg.

Stretch too much

These are very well made and soft. I would totally love them if they didn’t stretch so much at the knees and become baggy after I’ve slept in them. They should stay next to the skin for the best warmth. Also the waist band is rather tight. I’m 5’ 8” 135 lbs and got a M

Great in an unheated factory

I work in a mostly unheated factory at the truck dock, so need a coat, hat and gloves at my desk. I got a pair of these and was so warm I got a second pair as soon as possible. The colors were also very rich and eye appealing altho no one sees them!

Not the same!

Last year I bought a Minus33 light-weight wool crew top and absolutely love it. Hence, this year I wanted to get a mid-weight wool crew top and asked for XL again. I am disappointed that this new XL is baggier (bigger) and the neck line does not cover my shoulders as well as the previous top, as it too is bigger than my first one. It is a nice top, but I feel like my neck is not nearly as warm with a larger neck line. I guess I should have ordered a regular large.

The shirt is warm and very nice, but it isn't quite what I expected.
