These All Terrain Gel Kneepads are as effective as those red rubber knee things you see on roofers and floor installer guys. There are two big differences. These are comfortable and a lot prettier. They WILL protect your knees. When I ran a garden shop, one very discerning customer pulled off the packaging, strapped them around her knees and proceeded to "kneel" around the store. They worked for her and she drew a small crowd:) They're attached with Velcro so they're easy to put on and take off. It's a good professional product available to home gardeners. The color will be a surprise! It will be red, green or blue.
