My husband used them in a race recently and said they were perfect.
First I bought a pair of Nike arm sleeves. Had to return them because they kept sliding down. Zensah’s arm sleeves fit so much better. They stay up and compress well. Love them and will recommend them to my running friends!
Really like these. I only wish you also had a model with thumb holes and a longer length for slightly cooler weather. Fabric is nice and stayed in place perfectly.
They are super comfortable and I don’t even realize I have them on! Plus they are warm too. Great product!
The purchasing experience was online and seamless. The sleeves have functioned great, even with 30-40 F. Much better way to vent some heat yet keep my arms warm. Will use on my next marathon. One upgrade would be an access point for a wrist based fitness tracker garmin, Fitbit, apple watch etc. The wrist elastic does make it harder to access and see your watch, check pace and distance. Thanks for a great product and buying experience Zensah
