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.

The shirt is soft and comfortable and runs true to size

The shirt is soft and comfortable and runs true to size. I like the v-neck because I prefer not to show my tee shirt when wearing a button up the front shirt. I like the fact that wool continues to insulate even when it is moist from perspiration. This is important when exercising in cold weather.

That's wonderful feedback! We're so glad you love the softness and true-to-size fit of the shirt. You hit on exactly why we love merino wool- it is perfect for layering, and the fact that it insulates even when damp is key for staying comfortable and safe while exercising in cold weather.

V-neck merino tee shirt is very nice !

See title. The large size seems on the smaller side but no need to return it.

Thank you for taking the time to leave us a review! We are glad to hear that you are enjoying the shirt. We apologize if the sizing was smaller than expected, but we are happy to hear that it did not warrant a return. Thank you again for your feedback and for being part of our Minus33 family!

Top notch weave

I don't know what it is about the Minus 33 lightweight weaves but they seem to be more comfortable and breathable than other brand. This is a versatile undershirt or t-shirt. My only wish is that the length was just a bit longer.

Dannyboy,

Thank you for taking the time to leave a review for our Micro Weight Woolverino Men's Wool V-Neck. We're glad to hear that you find our lightweight weave to be top notch and more comfortable and breathable compared to other brands. We appreciate your feedback regarding the length and will definitely take it into consideration for future improvements.

Lightweight Wool T-shirt

I'd previously purchased two of these T-shirts and really like them. While the material is about the same on this latest purchase, the stitching at the shoulders is not quite right, and the fabric puckers a bit, rather than laying smoothly. Probably a QC issue.

Roderick,

Thank you for taking the time to leave a review for our Woolverino Micro Weight Men's Wool V-Neck T-Shirt. We're glad to hear that you've previously enjoyed this product.

We apologize for any issues you experienced with the stitching on the shoulders of the new item(s) on your latest purchase. Quality control is something we take very seriously and we will definitely look into this to ensure a better experience for our customers.

Thank you for bringing this to our attention and for being a valued customer. Please don't hesitate to reach out to our customer service team regarding a warranty claim for these items.

great undershirt

I use this mostly has a sleep shirt. I've had it for about a year and a half and its held up great. I'm 5'11"/195 lbs and a medium is fine as pajamas. I wanted it to be able to double as a work out shirt but would probably go up to a large for that. I have the t-shirt version of these that are also great.
