Minus33 Clothing Review

I received Minus33 products from the company to test and review. All opinions are my own and I only write about products I believe will benefit my readers.

I’m going to start by saying that I love wool. It’s my go-to fabric when hiking and backpacking, so I was excited when I came across Minus33 and their innovative products.  

Minus33 makes superior quality products at an affordable price. Their mission is to make everyone feel comfortable and prepared in the outdoors, including having reliable gear. My first Minus33 product was a wool hat, and I was sold. It’s so lightweight, yet one of the warmest hats I own, and it stays down over my ears.  

Why I love Wool 

Wool is a wonder fabric that can keep you warm when it’s cold and cool when it’s hot. It does this by wicking moisture away from your body while providing insulation. Even if it gets wet, it will still provide insulation.  

Among the many benefits of wool is that it provides UPF protection and is anti-microbial resistant which helps reduce odor.  

Merino wool, which is what most outdoor clothing is made from, is also soft and shouldn’t itch.  

And wool is biodegradable and renewable, so it’s a better choice for the environment.

Minus33 Product Lines

Minus33 has four fabric weights: micro, lightweight, midweight, and expedition. They have a handy chart on their website to help you find the right product based on activity level and temperature.  

Since I live in the southeastern US, I would be at activity levels and temperatures more suited to micro and lightweight materials.  

Beyond that, they have two different fabrics, 100% Merino wool, and Woolverino (84% merino wool, 12% nylon, 4% spandex blend).  Woolverino feels smoother and should be more durable than 100% Merino wool. The wool is wrapped around a nylon core, so you have wool against your skin.   

Woolverino products are available in micro and midweight densities. The 100% Merino wool products are available in lightweight, midweight, expedition, and wilderness expedition weights, 

They also have a Wilderness Expedition line which is 100% Merino Wool but weighs less than the classic Expedition line and is twice as durable. The secret is a special double-layer Ponte knit.  

What I Like About Minus33 

First up, I love their website. They don’t hide information. Everything you need from where the wool is sourced to the benefits of wool to understanding the brand and its products is easy to find.  

They also offer a unique way to recycle your old products. Once a product reaches the end of its life, you can donate it to their Search and Rescue Kit program. The program creates head-to-toe outfits of warm clothing that go on Search and Rescue (SAR) missions. This allows the SAR team to dress victims in warm clothes so they can begin warming up immediately.  

If you like to touch and feel a product before purchasing, they have retailers throughout the US that sell their products. You can check their store locator to find your closest retailer.  

And to top it off, I had the pleasure of meeting some of the team at a conference and they all love the brand and proudly wear it.  

Products Tested 

The Minus33 team was kind enough to ship a few products so I could test them out in the field.  

Minus33 Socks

Wool Day Hiker Crew Socks Midweight 

These are nice thick socks. Minus33 did a really good job of making them thick where it’s needed and thin where you don’t need as much padding. Unlike some of my other thick hiking socks, these didn’t make my boots feel tight.  

While they look a lot thicker than the Mountain Heritage Boot Wool Socks, I switched them out on my second day and didn’t need to readjust the boots. My feet were toasty warm in the socks, but not overheating.  

These socks were so comfortable, I broke my own rule and wore them around the house. Usually, hiking socks are only allowed out for hiking.   

I’ll be purchasing another pair of these.

Mountain Heritage Boot Wool Socks All Season Lightweight 

These are the socks I instantly wanted when I saw one of the Minus33 crew wearing them. Not too thick, not too thin, perfect height, and cushioning at the toe and heel. And I mean cushioning.  

I took these on a 10-mile training hike with 25 pounds of weight and they protected my feet all day. No blisters, callouses, or hot spots. And they stayed up. My socks never stay up.  

Two weeks later, they went on a backpacking trip, and once again, I didn’t think about my feet or my socks. You really can’t ask for more than that.

Woolverino Women’s Wool V-Neck T-Shirt

I’m in love with this micro weight shirt. I can’t find the words to describe how light, silky, drapey, and airy this shirt feels. Yet it holds its shape rather than just hanging like a blob.   

There’s zero itch and it’s so thin and light that you don’t feel it under layers. I wore it hiking in 40-degree weather under a long-sleeve heavier weight shirt and didn’t feel the Woolverino V-Neck at all.  

It simply grabbed my sweat and wicked it away while feeling buttery light. I’ve also worn it backpacking and feel confident the fabric is durable and will hold up over time under the weight of the pack. 

Using their sizing chart, I went with a medium that fit perfectly. For a true base layer, which should fit snugly, I’d probably get a small. But the medium is great for heading out on the town, wearing on day hikes, and backpacking in the summer.

I can already tell that this is going to be my go-to summer shirt. The lightness of the fabric and the way it drapes will be perfect for 100-degree days with 75% humidity (welcome to the south).

Woolverino Women’s Wool Leggings Midweight

There are so many words I want to use to describe these leggings, cushy, spongy, soft, warm, and possibly plushy. But they’re not heavy or super thick. When you pull them out of the pack they feel thick, and they keep you warm as if they were heavy, but they’re normal wool leggings. It’s hard to describe.  

The Wooleverino leggings are 235 gsm, so less than my normal leggings of 250 gsm. Yet I found them softer, warmer, and more comfortable for the same number of ounces in my pack. I’m a side sleeper and the back of my legs often feel cold. When I tested these at 40 degrees, I didn’t get that feeling. I was warm all night.

And when I say they’re comfortable and warm I mean that I got out of my tent to use the bathroom and make coffee and forgot to change into my hiking pants! 

Here again, I used the size chart and went with a large that fit well. I may have been fine with a medium, but the size large was comfortable and I liked that they didn’t grip tightly. 

To sum it up, they’re soft, comfortable, keep me warm, and weigh the same as other, more expensive leggings.

Minus33 Clothing Wrap Up 

I know I used the word love a lot when describing the Minus33 clothing, but it’s the best way to describe how much I like their products.  

I’m really picky about my hiking and backpacking gear. Summers here are so hot and miserable that you need lightweight gear that wicks sweat and controls odor. And in the winter we tow a line between too cold to keep layering your three-season gear, and not cold enough for Colorado winter gear. It’s difficult to pack the right clothes without breaking the bank.  

But Minus33 really hit everything just right. The micro weight is perfect for summer and layering, and the midweight is just what we need for our southeastern winters. Plus, everything is well made, and the fabric texture is soft and silky.  

On top of that, their products are affordable. True to their mission, they make great gear so everyone can feel prepared in the outdoors. I can get behind that.  

I love their clothing so much, I included them in my top Wool shirts for hiking and backpacking, and my picks for best hiking socks!

I can’t wait to build out my backpacking wardrobe with a few more items.
