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.

XS is suitable

I am 5'2'' with 99 LB, XS is suitable to me, the length is supper! But the true RED is not red color I expected exactly like Moncler company, and this shirt looks thin, not as shown in the picture. This is my first time purchase from Minusm33.

Ling,

We thank you for your insight. If you are not pleased with the color of your Minus33 purchase, please contact us so we may assist you further.

Very nice garment

Light weight - just used it as a base layer for ice skating, which I do year round. Pleased with the fit and the softness!

Hi there! We're so happy to hear that you're enjoying your Microweight 1/4 Zip Woolverino! It's great to hear that it's working well for your ice skating needs. Thank you for sharing your feedback with us. Have a fantastic day!

Warm and Comfortable

I let go of an IBEX top that had run its course and needed a replacement. I am hooked. The top is lightweight, great for layering or wearing alone, comfortable on the skin, and warm! I use it primarily for late fall and winter running. I am so pleased to find a locally owned and operated company that offers products with such integrity.

Sara,

Great top!

I bought this top for a trip to go to the Might 5 National Parks in Utah. It worked perfectly for sun protection while keeping me cool as well. I’m 5’4”, 143 lbs and I got a medium and it fits perfectly. I really wish y’all offered it in more colors, like the mint I see for the microweight hoodie.

Thank you so much for leaving a review for our Micro Weight Woolverino Women's Wool 1/4 Zip. We are thrilled to hear that it worked perfectly for your trip to the Mighty 5 National Parks in Utah. Our top is designed for sun protection while also keeping you cool, so we are glad to hear it did just that for you. We appreciate your feedback about offering more colors, and we will definitely take that into consideration for future products. Thank you for choosing Minus33.

Oh so comfy!

This is my second purchase of the 3/4 zip micro weight, and I'm in love with it! It is incredibly soft, has just enough stretch, and fits great. I live in a warm climate and use this as my "go to" light weight shirt when it gets a bit chilly. It folds well and small and I stick it in my backpack for airline travel in every season. I'm 5'4, 116 lbs and the small fits great. It's loose enough that I can pull it over a short sleeved or long sleeved shirt for layering, but not too loose that I can't wear it over a tank top. It has perfect stretch. It's so soft, I can believe it's really wool! The zip is very long, which is great for controlling how warm or cool you want to be, and for ease of pulling it over your head. Because it's so soft and thin, the collar does not stand up when it's unzipped, just an observation for others. It washes very well and kept its shape nicely. Please Minus 33, come out with more colors and I will buy them all!

Jean,

Thank you for taking the time to leave such a lovely review for our Woolverino Micro Weight Women's Wool 1/4 Zip. We are delighted to hear that you love it and have made a second purchase. It's wonderful to know that it is your go-to shirt for chilly weather and travels well. We appreciate your detailed feedback on the fit and functionality of the shirt, and we are glad to hear that it washes well and maintains its shape.

We have taken note of your suggestion for more color options and will definitely consider it for future designs. Thank you for your continued support!

Sincerely,

Warm in a San Franciso Summer

I bought this for my daughter for a backpacking trip. My wife borrowed it for a trip to see friends in the Bay Area and loved it. Light, comfortable, and warm -- a perfect mid-layer.

Thanks for the review! We're happy to hear that your daughter and wife love the Micro Weight - Women's Wool 1/4 Zip Woolverino is warm and comfortable and perfect for a mid-layer.

Good, but short not as good as the other products

The shirt is comfortable and I wore it Nordic skiing as well as around the house a couple times. I received the lightweight xs crew neck shirt for Christmas and wanted this 1/4 zip for skiing. It is hard to describe why, but immediately upon receiving this shirt it seemed different as if from a completely different, but similar producer. I assumed this shirt would be similar to the crew, but it is shorter than the other shirts. For example, I am wearing high waist jeans and this top rolled up above the jeans. The arms are good length, maybe a bit long, which is normal since I am actually a petite size.

Casey,

Thank you for taking the time to write this review. We apologize for any disappointment that you may have with the fit of your Minus33 Liberty 1/4 Zip. We have a new fit coming out in the summer of 2022 that may suit you better. If you would like to contact us to initiate a return please call 603-968-3351 and Customer Service Representative will gladly assist you.

High quality, almost perfect

This is a really nice layering piece. Comparable or better than any other brands I have tried.

However, I found it sized small compared to my midweight tunic, which would be OK since I wanted to wear it as a base layer. But I ultimately returned it because it is not as long as my midweight crew.

I really enjoy a top that stays tucked in, covers my bum, and doesn't expose skin when I raise my arms

Customer service was exceptional & I look forward to comparing the length of this one to other light or micro weight tops

Love this shirt!

This shirt fits great, feels awesome and keeps me warm even though it is lightweight. I got the red. The cut and seams are very well done. I’ll be ordering this in other colors, Please make more! Cobalt blue would be nice :) I’m 5’3” 145 lbs and the large fits perfect.

lightweight warmth

I love how light weight this 1/4 zip is. The heavier weight ones tend to be a bit tighter and feel somewhat constricting (which is fine when you are really cold), but this weight is great to have to throw on for a bit of warmth or even to wear as your shirt of over a cami.

Glad you like it. Thank you for taking the time to leave a review.

lovely product

I found the medium in the light weight to be small compared to the medium i purchased last spring in the mid weight.

Sorry it didn't fit quite right. If you would like to exchange it please reach out to us. Thank you for your review.

How does the shape and material hold up after a year of wear? I have another wool brand with mixed fibers and the shirt is now stretched out and gigantic

Minus33 Merino Wool Clothing

Sam,

Thank you for your question. I'd like to also share some details about our woolverino fabric with you. The Woolverino collection is our blended 84% merino wool, 145gsm fabric. The wool has a nylon inner core that provides extra strength and resiliency, as well as extra elasticity, which helps achieve a tighter, athletic fit to the body.

The merino wool on the outside of the nylon core keeps insulation, moisture wicking, and UV protective properties next to the skin so you can still reap all the benefits of merino wool.

When following the suggested care instructions that come listed on the these garments, they should hold up well after a year of wear.

Please let me know if you have any further questions.

I am looking to replace my icebreaker 'skin200' part-zip top, which I've had for may years but is starting to get tears. I see 2 weights of these tops on your website and wonder if your comparable weight is the lightweight or midweight - I suspect the lightweight. I wear this cross country skiing (with a fleece and jacket) and am very warm and often remove the fleece, so i don't need a very heavy weight in this garment. Thanks for your assistance.
