My wife and I both snagged a pair of these for some last training rides in humid weather prior to our Fall races. We were both finding that our hands were beginning to slip a lot off of the aero extension grips as the humidity climbed. We wanted the extra safety feature as we rode larger hills in our races. We ordered them and they came just in time for our last rides so we could get used to them prior to our races. They are comfortable and have a very simple design. We appreciate no Velcro or fasteners which add seams. Their clean design also goes well with a race kit so you still feel cool on race day! We didn’t notice much difference between the size M, L, or XL so opted for the size L as we both have larger hands. I will likely wear them only in more humid weather but I expect my wife to begin wearing them anytime she rides. Great, simple gloves!
