Stealth grips are made of a high-performance synthetic microfiber that is 3 times stronger and lighter than leather with a higher abrasion resistance. Therefore, we are able to make these grips thinner than leather providing a barehanded natural feel and full protection. The Stealth grips will not stretch like leather and will hold their shape more consistently. They are slightly longer to accommodate for the fact they do not stretch. Additionally, they are microporous, allowing water vapor and heat to pass through allowing them to deal with sweat very well. Stealth grips can be washed by hand or in a gentle machine cycle, and allow to air dry. They are also vegan-friendly!
