• For cold weather - Heavy winter gloves increase the gripping force necessary to securely hold hard faced tools, so these grips are a great way to reduce that force, reduce hand fatigue, and risk of injury.  They also help insulate your hand from the cold metal.  It's no fun gripping a steel wrench when its been sitting in your truck all night at -10F, and these grips really help.
• For hot weather - Dark steel tools can get really hot in the summer sun (over 130 F) and these grips keep your hands away from the hot metal.
• For rain - these grips work well when it's wet, and are much better than trying to grip wet steel or aluminum.

The grips are made out of an open cell polymer material that looks like it will last.  It’s washable, but it doesn’t retain water like a sponge.  The material gets a little stiffer at freezing temperatures, but it still works fine.  To put the grips on just wet the surfaces with water, slide it on, and let it dry. 

There are three sizes: Small, Medium and Large to fit a wide range of hand tools from small crescent wrenches and screw drivers up to 36” pipe wrenches.
