The Merino Wool Advantage

Merino Wool has plenty of natural properties that give you a distinct advantage over synthetic fabrics.

Mouse over our flock of sheep below to learn more about each one.

Moisture Wicking Merino Wool Sheep

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.
Natural Flexibility Merino Wool Sheep

Natural Flexibility

Minus33 Merino Wool clothing is naturally elastic, allowing it to stretch to your movements. Our goal is to give you comfortable, breathable, soft, wicking layers for any trek you embark on.
Odor Resistant Merino Wool Sheep

Odor Resistant

With less moisture comes less odor. No more worrying about smelling bad while wearing Minus33 Merino Wool. Merino Wool fibers naturally reject any bacteria in moisture or sweat as it is wicked away.
Controlled Felting Merino Wool Sheep

Controlled Felting

All natural controlled felting, milling or fulling is a finishing treatment used on Merino Wool to achieve a number of effects including increased thickness, strength, and reduced air permeability.
Fire Resistant Flame Retardant Merino Wool Sheep

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.
Renewable Biodegradable Merino Wool Sheep

Renewable and Biodegradable

Merino Wool garments are biodegradable and return to their natural elements. Shear a merino sheep in the morning, and in the afternoon they’re happily nibbling their way towards renewing next season’s clip.
UV Protection Merino Wool Sheep

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+.
Anti-Microbial Merino Wool Sheep


Minus33 Merino resists against microbes and odor, so foot fungus and smelly odor will NOT be a problem while wearing our products. Our state of the art wicking ability absorbs moisture and releases it back into the air.
Insulates When Wet Merino Wool Sheep

Insulates When Wet

Wool will absorb up to 30% of its weight in moisture. If you do get wet, wool will insulate you better than cotton or polyester materials.
