ABOUT US
In 2002, Minus33 was created by textile engineers from L. W. Packard & Co. Inc. L. W. Packard has been involved in just about every aspect of the wool industry, and a proud family-owned business since 1916. In 1995, L.W. Packard was selected by Textile World magazine as one of the top ten textile plants in the world.
With so much of our family history rooted in the wool industry, combined with our genuine passion for the outdoors, it only made sense for Minus33 to emerge as a merino wool clothing brand. Minus33 began as a snowmobile brand, and quickly expanded to other outdoor markets, such as hiking, skiing, and hunting due the versatility of our product offering.

WITH YOU THROUGH IT ALL
Our Midweight styles have all the same natural qualities as our Lightweight Merino Wool, with greater insulation. Minus33 Merino Wool Clothing is perfect as a base layer for a day on the slopes or as an emergency pullover when a cold front rolls in just before you summit.
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.
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.
The Chocorua Midweight Crew
Don’t sweat, this will be your favorite shirt to adventure in no matter the time of year. Our #1 selling top provides warmth, breathability, and ultimate comfort for any occasion. Wear it as part of a layering system in colder temperatures or by itself when the sun comes out. Pair it with our Kancamagus Midweight bottoms to create the ultimate base layer set.

***This is my initial review after receiving the package and wearing the product. I bought this for hunting season in PA as well as skiing season here in NJ, and will be able to test it further and update this review by the end of the year.I bought this product because I am tired of looking and feeling like the Michelin Man during hunting season with my puffy down clothes and multiple layers. (Bought together with Katmai Men's Expedition Bottom). I want this to be my base layer, and then simply wear my hunting jacket over it. Skiing I've never had a problem wearing just a t-shirt and a jacket and actually wind up sweating because of the movement and I am always warm in general. But something about sitting in one spot while hunting really lets the cold seep in. I won't be able to update this review with how well it performs until the end of 2015, but here are my initial thoughts:Packaging: The packaging is simple, compact, and came with no issues.Fit: I'm 5'5, 140 pounds and have a waist size of about 29/30 inches. I bought a small, and both this top as well as the small Katmai bottoms fit perfectly. Tight fitting (how I usually like my clothing, especially base layers), but extremely comfortable and hugs the body well. The only thing you may have a problem with is that the sleeves (as other reviews have mentioned) run a tad short. If you stretch your arms out for example, your wrists may become exposed a bit. I love the fit, and this isn't an issue for me. Just throwing it out there for someone who may not feel the same.Warmth: I noticed as soon as I put these on, my entire body felt cooled down. This to me is a good thing, as it means instead of just trapping heat and moisture, the wool is allowing my body to breath while still retaining heat. To confirm this, I took everything off and felt the inside and they were very warm to the touch.Quality: The quality of the product is very good. The material feels good, looks good (good enough that you could actually wear this top in public with a nice pair of jeans and not feel strange about it) and even the tag is printed onto the shirt so there is nothing scratching at your neck.So far, I am very satisfied with this product. I will update when I can, and if it performs well I will be ordering more of different weights for the different seasons (even summer) because I really like the quality, fit, comfort, and breathability.

Know how foreign clothes manufacturers scrimp on length I ordered a 2X tall to insure that it would stay tucked in. Was I wrong! It would have worked for an NBA player. I ordered a 2nd one in regular and the sleeves and body length are superb. The material is soft, warm and the stitching is spot on.

The Minus 33 mid-weight, medium sized, long sleeve crew shirt is a wonderful layering piece.I like the fit for my medium size torso. I am 5’ 10†tall, 145 pounds and wear consistently, medium shirts.I have been using this this top layer over a Minus 33 Micro 1/4 zip T, which has been very functional while out snowshoeing in 24-40* temperatures. Yes, I have added a soft shell vest as needed along with my Minus 33 Ridge cuff beanie, Neck Gator, and fingerless gloves.What I like about the fabric of these shirts is, they have a smooth surface which tends to help them layer well. The arm lengths and body were comfortable. The pieces kept me warm and dry and for me, controlled Oder well.It’s worth noting that, I had also just bought a new Minus 33 micro 1/4 zip T to replace the one I had tested for Minus 33 well over a decade and a half ago and was still happily using. The new 1/4 zip T is functionally better especially with how well it layers-as is the medium weight mid-layer this review is about.

A year ago I bought one of these. I had reservations because $80 can be a tough sell when you are shopping online and can't actually feel/try the item yourself. Well it turned out to be a good buy so I'm here to get another.Working on a flight line at an airport, so I can be outside for a few minutes or for hours on end so they make sure we have good outer layers other than base layers. For the longest time I had just regular tees underneath it all but I heard from friends and around the internet about how nice wool can be if it's the right type, and they're right!By itself the shirt is cozy but breathes enough to keep it from making it super hot. When it's cold you're supposed to avoid working up a sweat but if I do and then cool down again the shirt absorbs the sweat and mostly prevents me from getting chilly. We are usually stop and go so it's very nice for my use case.The fabric is stretchy so it never feels tight even when I'm in weird contorted positions. Be warned though it can be delicate so try to keep it away from hook parts of velcro, sharp metal/wires, cat claws, thorn bushes, etc. Take care of it and it will take care of you

My go to shirt for hiking in the colder months. As warm as hoodie but half the weight, and soft as can be.

Wool products are my favorite. Blankets, sweaters, coats, merino, cashmere, etc. This 100 percent merino is among the best merino I've ever purchased even amongst high end retailers. I'm ordering a second.Gorgeous black. Takes chill out instantly. Love it, love it.

Very nice product. Thick wool. Fits perfect to size. Feels like a warm cloud, soft warm and airie. (Is that a word?)Good value unless Minu33 price in options 2, 3, or 4. Buyer beware! Check for holes. Maybe moths.

Dislike the quality of the product , the material is far too lightweight and rips extremly easily. I do not recommend purchasing this item.Was not able to return the item to Minus33, the warrantee is not comparible to other suppliers Warrantee.I highly recommend purchasing from another Merino Wool distributer.

Super comfortable, soft and warm, without making you sweat. I washed it a few times so far (turned inside out), and it looks and feels just great.A sizing chart added to the photos would be nice though.
