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.

Tall Sizing is Actually Tall!!

I tried other brands of “tall” Merino shirts that weren’t very tall, this is not like those at all! I’m 6’6” and the sleeves are almost TOO long and the torso is nice and long too, perfect for going under a bottom base layer. They are pricey but the wool seems softer than a few other brands I’ve tried too. Time will tell how they hold up. At $105 these tall sizes aren’t cheap but they are worth it to me to have actual well-fitting clothing!

Comfy shirt AND a warranty? I’ll take two!

Great feeling T-shirt in a Tan499 option for uniformed personnel!! I’ve been wearing Under Armor shirts and underwear under my uniform for 15+ years and felt it was time for a change. UA’s quality seems to be going down and I wanted a natural, renewable fabric that would wick sweat. Merino was my answer and then some since it’s also anti odor and fire resistant. I searched and searched and even spoke to a few companies on the phone about making a Tan499 shirt. Minus33 was one of two companies that made T-shirts in a tan color. Minus33 is the only company as of this review that makes a Tan499 option. And it being a U.S. based companies in NH is icing on the cake. The feel is light and breezy, it’s not quite as soft as cotton but still really soft. It’s a different kind of softness (if you can imagine that). It’s stretchy kind of like spandex and fits snugly but not tight. (Think Under Armor loose gear if you go down a size). The price on these may seem high but since they can be worn multiple days between washing it’s comparable to the price of under armor T-shirts. I got 2 long sleeve and 2 short sleeve and that works great for me. Now if Minus33 would just make a V-neck So I could switch my everyday shirts to merino...I left one star open because I’ve got some merino that is a bit softer feeling. If this gets softer after a wash or two I’ll come back with the 5th star.

Excellent Product!

We are hunters and we have a big vacation planned in the near future going to Yellowstone National Park in the Winter. I live in Louisiana where our cold is a wet cold. But in Montana it is a dry cold. After reading many informative documents on how to dress for the cold and the extreme cold in Montana, I knew I needed to purchase some clothing made from Merino Wool. Merino wool wicks perspiration away from the skin. I don't need my my husband getting out in the cold and getting wet only to get pneumonia! Keeping dry helps to avoid hypothermia in the winter.I ordered my husband the tops and bottoms in the Mossy Oak Camo pattern in large. The fit is perfect. He will be using these as his base layer. This top is lightweight not bulky like I thought it would be. It is very soft and comfortable – not itchy at all. When I think of wool, I think of the heavy, thick, itchy, bulky material but not this 100% Merino Wool. The stitching is done perfectly. I washed his as soon as I received them in cold water and tumbled in the dryer on low. He has tried them on and is very pleased with them. He has not had the opportunity to wear these in the cold yet – still 100 degrees here in Louisiana but he has been wearing them in the house just to make sure they fit and are comfortable. They have passed that test and they are very warm so he can't wear them for long right now. I highly recommend this product. I paid full price for this item but a day after I purchased these, the price went up.

Yes To Minus33!!

This was my first order from Minus33 and since then have placed and received three other orders. I have been wearing merino wool items for a long time from other vendors and wish I knew of Minus33 when I first began wearing merino. Minus33 has become the vendor of choice for me.

A Perfect Combination of Warmth, Comfort, and Quality!

I couldn’t be happier with my recent purchase! The Minus33 Men’s Wool Thermal Top is hands-down the best base layer I’ve ever owned. The 100% Merino wool feels incredibly soft against the skin. No scratchiness at all, and it keeps me warm without overheating. It breathes beautifully, wicks moisture when I’m active, and still looks great after several washes. The fit is true to size and allows easy layering without feeling bulky. This has become my go-to piece for everything from brisk morning walks to long work shifts outdoors. You can really tell the quality with its durable stitching, excellent fabric, and thoughtful design. Minus33 knocked it out of the park with this one. I’ll definitely be back for more colors soon!

Soft, Well-Fitting Merino Top That Delivers Reliable All-Day Warmth

The sizing was accurate and the fit is comfortable without being restrictive. The merino wool feels soft against the skin and provides consistent warmth without overheating. It works well as an all-day base layer rather than something you’re eager to take off. Shipping was fast and problem-free. Based on this experience, I fully expect to purchase another top.

“Come on man!”

Two only because it is a soft wool under shirt so it’s obviously going to perform better than synthetic or cotton. But seriously from China! I will not support that especially from a company here in NH. Minus33 you can do better resourcing. This will be my last purchase
