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.

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.

Customer Reviews

Based on 17 reviews

Snug to the neck, soft, long and limber for rockclimbing, but the hood is useless as a cold-weather baselayer. The hood doesn't cover the forehead, doesn't cinch around my face even zipped to the chin. It's a mid-weight hoodie, covering the head - including the forehead - is the point, especially for an outdoor performance garment otherwise dialed pertinear for four seasons. The hood feels like an afterthought, like they couldn't be bothered to add the extra inches and hone the shape. So disappointing. Minus 33 is refunding me.

Everything I have purchased from this company has been beyond impressive… This coming from a guy that fishes ALLOT when it’s below freezing…
By far, the finest wool, and garment cuts of any outdoor company I roll with!

Another great product

Well made. Perfect and performs as advertised. Not itchy at all which was a concern for me. The hood is lined with fleece, a great design for the hair follicle challenged It's slim and fits well under an outside layer. It's snug so go up a size if you want a more comfortable fit. Couldn't be happier

Thank you so much for taking the time to leave us such a great review on the the Woolverino Trailblazer Full Zip Hoodie - Midweight. It is one of my favorites as well!

It’s ok, But, despite the quality……

I’ve been purchasing and wearing Minus 33 sweaters for years. So has my wife and my friends. The sweaters were merino wool, black, full zip, thum holes in wrist bands, mock turtleneck style, 2xl. And than u stopped making them. We are all disappointed. The new ones are designed for the young, fit, cross country skier. And your 2xl is more like xl+ (maybe).

Everyday Piece

This hoody is perfect for those cooler days when you need an extra layer that will knock the chill off and not overheat you while you’re active. I mostly use it for hiking and running but it’s hard to not grab this thing every time I head out to town and it’s a little cool outside. If you’re looking for a nice looking hoody that you can use for running when it’s below freezing, a mid layer when your static in the cold, or throw on and run to town when you need an extra layer then this it. The material is very soft and stretchy and the fit is trim. I’m 185 with an athletic build and the large fits perfectly. The only thing I’d like to see is more color options…. Hook us up Minus33!

Hi Merle,

Thank you for taking the time to leave us such a great review. We are happy to hear that you are enjoying the fit and performance of your Minus33 Woolverino Men's Full Zip Hoodie.
