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. 



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.

Ill Fitted

Warm, comfortable either alone or under pants, and sized perfectly. Unfortunately the rise is cut too short and rides low on back so that I constantly pull them up. I had to double check that I didn't have a man's base layer. A pocket on the leg would be helpful. These would be great for a runner, but not the average woman.

Thank you for leaving us a review. I'm sorry that our wool bottoms weren't a good fit for you . If you would like to make a return or exchange please reach out to us. We have both a 30 day guarantee as well as a 1 year manufacturer's warranty for situations just like this. Please let me know if you have any questions!

Kenai leggings not the same

I have 2 other pairs bought a couple years ago
These are totally different
Not as warm
Shiny. Outer cover
Inside not soft

Marni Matyus
Amazing quality

These feel like a nice pair of knit dress pants. They fit like my favorite yoga pants.

I did size up and they are perfect.
I desired a looser legging for layering and wearing under dresses.

I can fold up the cuff and wear these to work with a tunic, a pair of flats, or warm boots. I can layer a snug pair of lightweight leggings underneath, I can even layer the same size midweight leggings underneath.

I wear them alone (with a tunic top) for daily wear, layered over a thin base layer for camping, orwith a pair of hiking pants on top to protect the lovely fabric.

Soft to the skin, but for active wear I would wear a thinner base layer underneath.

For leggings while at work, or for sleeping in my hammock, they are perfect

5'6 165
33-34 waist
40-41 hips

I purchased the xl & love them, but they are not snug fitting.i would buy the large if I wanted a close/athletic fit or if I wanted to layer more items on top.

I prefert to wear these as a mid or outer layer

Wish there were more colors!

I've worn these pants the past few winters, and they're perfect and comfortable for a NY winter. I only wish there were more colors!


Thank you for the great review!
