Abrasion resistance ratings are often used to evaluate the durability of a glove –that is, how long a glove will last in the field, when used for a variety of tasks. This is a key metric, because glove durability directly affects the overall cost of hand protection programs. The math is simple and effective: a $30 glove that lasts 6 weeks is three times as cost effective as a $15 glove that lasts one week.
