Warm, breathable, moisture repellent and anti-static, Merino has the capacity to deal with moisture like no other yarns, absorbing perspiration and releasing it into the air as vapor. It is naturally odor resistant too. Luxuriously soft and gentle against the skin, it reacts to your body’s temperature, keeping you warm when it’s cold and releasing body heat and moisture when it’s hot. The natural elasticity and resilience of Merino wool enables it to spring back into shape with ease. 

DexShell only purchase and use merino wool that is guaranteed mulesing free.


COOLMAX® is the performance yarn that includes an effective fiber based moisture management system. The system can move perspiration away from the body, through the fabric, and transfer out of the wear. It can evaporate quickly, allowing the wearer to feel cooler and much more comfortable. 

COOLMAX® is the registered trademark of Invista®.


drirelease® technology uses an engineered blend of multi-denier, multi-staple length hydrophobic and hydrophilic fibers to keep wearers dry, cool and comfortable. The unique blend of synthetic and natural fibers in drirelease® yarn actually accelerates the water release rate. The drirelease® WOOL blend is as warm as 100% wool without the itch. The wearer never feels clammy against the skin.

The drirelease® DriFil is a new technology which optimizes both the comfort and durability. drirelease® is the registered trademark of Optimer Brands.
