Made of 100% spring crimped nylon material. It will not fade, bunch, weather or leave marks on your clubs. Our Emerald Chip golf mat is 1" thick with a 5mm foam backing that will withstand repeated abuse. Our dense fiber mat allows you to feel the difference on a fat shot because if you go to deep the thick fibers will slow your clubhead speed resulting in a fat shot. In practice you will learn to eliminate your mishit shots. Our competitors golf mat will "bounce" which will result in mishit shots. NO BOUNCE! NO SHOCK! Our mat lets you hit down on the ball for better practice. All mats come with two rubber tee holes for either a right or left handed golfer. For indoor or outdoor use. Use with all or any club.
