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.

These hearty mid-layers are built to last with a double layer Ponte knit that is sure to beef up your next adventure.

Wilderness Details

Ponte de Roma is the name of a double knitting technique that consists of two layers of fabric knitted together. Ponte fabric is tightly knitted, making it very durable. It's stretchy, soft, doesn't wrinkle, and has a naturally flattering drape, which lets these mid-layers crossover perfectly from the outdoors to the office, and everything in between.

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. 



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.

Oh please... Please make your expedition weight merino tops in MAGENTA and in OFF-WHITE!! I have some black bottoms from a couple of years ago, and Love them!! But will not buy black tops. I hope I don't become old and grey before you get around to colour. Jehane


Thank you for the great review! We are happy to hear that you 'Love' our black bottoms. We will pass your color ideas on to our Production Development team.

Totally Amazing

Just the right weight and fit.I was worried about the fit as most companies have all athletic fit. I am a 65 year old woman beyond the athletic fit wear. Minus33 is the best quality. I like the 1/4 zips for layering.

Such a warm top too! Thank you for your review. Happy you are loving it!

Wilderness Expedition Women's Wool 1/4 Zip

I love this layer! I ski Wildcat and roam around the Whites. Finally I am warm yet not bulky. I am tall and not petite. Thank You for making a top long enough that stays in my ski pants, no gaposis on the chair and with enough wing span so I can move with ease while active ! Not everyone out hiking , skiing and playing in the mountains is one size . The quality is great. I will be ordering more. When I find something I like and this good , I stick to it! THANK YOU!

Finally an Expedition Weight in Women's

I run cold and have wanted to replace my Expedition weight bottoms and tops for years but hadn't found a good option. First of all the top fits well - I ordered a medium and am just shy of 5'9" and about 140 pounds and a small chest. I also have skin sensitivities so only the softest cottons seem to play well with my skin. Unfortunately this isn't the softest cotton so I have to wear something underneath to protect my skin - I'm not a big sweater so it works fine for me. I think for most people there wouldn't be an issue - you lucky devils! Anyway, I've been using it for bicycle rides in the high 30s,low 40s and it's done me very well. The quality seems exceptional!

Great jacket!

I liked the Minus33 full zip sweater so much that I also bought the quarter zip one. Warm, sharp looking, goes with everything, versatile.

Thank you so much for taking the time to leave us a review. We are so glad that the full zip is working well for you. That 1/4 zip will come in handy when you least expect it, enjoy!
