The Zip Grinder is a Breathable, UV Protectant T-Shirt that is made from Meryl fabric. The Meryl ensures that bacteria doesn’t develop and sensitive skin isn't affected.

Breathability. Two enviroments are artificially created with different hygrometic conditions and vapour is forced through the fabric, after wich vapour penetration is measured, with the result expressed in grams of water vapour per sq meters of fabric in 24 hours.
UVA Ray Protection. Meryl microfibre acts as a barrier, filtering the sun's rays wich are harmful to the skin and affording protection four times greater than that offered by polyester and twice that of cotton.
Ergonomic. These garments have a special cut and structure to facilitate body movement.
