How Does Minus33 Fit?

Our most common fit is called regular. It runs true to size and isn’t that super tight sport fit you might find with synthetic brands. It’s for the everyday person, every activity or occupation. We suggest purchasing the same size you would get in a basic cotton T-shirt or underwear.

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. Read more on our Fit Guide below.

Why Merino Wool?

Core Spun Technology

Core Spun yarn provides extra durability while still offering merino's properties next to the skin. The nylon inner core is wrapped with Merino Wool and a touch of spandex for stretch.

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.

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.

TOTAL EASY CARE

MACHINE WASH AND DRY

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.

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,

The Minus33 Team

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.
