A machine-washable, reusable, sterile, and extremely comfortable knit face mask to keep you safe. The StrongCore Merino face mask combines two world-class yearn technologies to create an extremely comfortable fully-knit face mask. The exterior of the mask is built from Nuyarn merino wool that spins ultra-fine merino wool around a durable nylon core. It is odor-resistant, dries 5x faster than conventional merino wool, is 47% stronger, and 35% stretchier. The interior of the face mask utilizes Meryl Skinlife technology regulates bacterial growth with silver nano-particles and ensures no bacteria can grow within the textile. The antibacterial treatment is permanent and is active against all main bacteria groups. The two materials are knit together with an open sleeve for adding a filter. Combined, the two yarn technologies make for a mask that will reduce moisture and heat build-up offering the wearer a more comfortable, moisture wicking, anti-bacterial face mask.
