      Product Story

      Adirondack [ad-uh-ron-dak]

      New York's Adirondack Region is the largest protected natural area in the contiguous United States. It is a welcoming home for skiers, hikers, boaters, and fishermen due to its seemingly endless offering of lakes, trailheads, and mountains.

      Couple Wearing Minus33 Midweight Merino Wool Base Layer Outfits

      Merino Wool

      Versatile and comfortable, our Merino Wool will always have your back. Designed as a three-season garment, our Midweight works great as either a base or mid layer.

      Midweight Details

      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.


      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.

      Juuust right

      Thin, light, warm. Perfect for when you want to be a little bit warmer, but not constrained by a heavy sweater.

      Thank you for your review.

      I Received The…

      I Received The Vest Yesterday, And Went Out For A Walk With It On, Over A Tech Shirt That Is Light, And Not A Real Cold Weather Piece. The Vest Turned It Into A Nicely Warm Combo. So Nice To Have A Piece Of Clothing That Can Be Combined With Other Shirts To Bring About The Perfect Amount Of Warmth. I Am Thinking Of The Minus33 Merino Wool Turtle Neck That I Have, As A Base, The Vest, And Then A Heavier Coat. This Combo Should Allow Me To Confront The Extreme Cold That We See Here In Crested Butte. I Also Think It Is Nice Looking, So All In All, I Really Like This Vest.

      XXL Sizing Perfect

      I'm 6'' 1', ~265, with a long torso. The sizing is perfect! (Minus33, please keep the length, it's spot on. Width is great too, but I really appreciated the length).
