Why Merino Wool?
Core Spun Technology
Core Spun yarn provides extra durability while still offering merino's properties next to the skin. The nylon inner core is wrapped with Merino Wool and a touch of spandex for stretch.
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.
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.

Hands down the best underwear I have ever owned. I bought them for hunting season and now they are the only ones in my drawer!
Thanks for the great review. We're glad the Woolverino Men's Wool Boxer Briefs - Micro Weight are a staple for you!
I live in Minnesota, winters are cold and long. Summers are hot and moist. Since I discovered these boxer briefs a few years ago, they have been my GO TO undergarments for all seasons. I have tried other merino underwear (Icebreaker, Duckworth, Smartwool) and these are by far the most durable and comfortable. 5 stars all day long.
We are happy to hear that our Minus33 boxer briefs are your 'go to' undergarment for all seasons. Thank you for this awsome review!
I just got these in and they are just as soft as the 100% wool but more roomy. I'm a fan!
We are happy to hear that you're enjoying your Minus33 Woolverino Boxer Briefs! The Woolverino line has some of my personal favorite items included in it and I agree that they are just as soft as our 100% wool items as well!
I gave these boxers a three star review, because of the fit. However, take it with a grain of salt, as I’m a weird body type. I’m a bit on the short and stout side, so it’s very rare that anything fits me properly. I followed the sizing chart on the site, but found them high very high waisted and saggy around the butt area, which would likely cause chafing during a long run or multi-day backpacking trip. I got them because I read a review that said they helped prevent thigh chafing (the short/squat man’s nemesis). This part held true. Though I had some annoying fabric bunching up around my butt, the leg portion stayed in place and kept my thighs from chafing.
Since they are underwear, and I assumed not returnable, I treated them pretty rough, right out of the box. I washed and dried them on high heat several times and they didn’t shrink or fall apart. I wore them for multiple days for hikes and runs and they held up just fine. My wife didn’t complain about my funk, so the merino wool anti microbial quality is pretty good too.
Overall, they’re a decent product, just be sure about your body type. I also have a lot of other Minus 33 products that have lasted for years and they’re really good products. It was just a bit of a bummer to spend 4 times more cash than I have ever spent on underwear to find that I can’t really wear it.
I bought two pair for September elk hunting when it's hot. All the great merino-isms (don't smell, comfy, etc) but have been more resilient than standard merino boxers regarding wear and tear.
