It seems like emergency workers spend a lot of working time on their knees. This is particularly true on heavy rescue operations, confined space entries, or tactical responses. Alta Superflex Knee Pads reduce stress and fatigue to the knees, allowing you to work longer and more effectively. Alta pads are lightweight, but have a full 1/2-inch layer of foam padding. The rubber caps grip the surface to prevent sliding. Unique buckle fastening system is easy to use and allows a comfortable fit that minimizes interference with circulation to the lower legs.
