I have used my vest and pad under my helmet and find them both to be comfortable and effective. I think I got them just in time as summer is really here in So middle Tn now. I also wanted to thank you for your prompt and personal service. My 8 year old niece is coming to visit on Saturday and she is horse crazy and I got the vest to keep me cool so she can ride w/o her Old(over 60)Aunt having heat stroke. I will be walking and "trotting" alongside!!! she will be here for two weeks, so the vest will get lots of use. Oh, I almost forgot; I love the color and the horse design. It is a very good looking vest, fits great, and works well. Thank you again for your excellent service. Ginny ...Tennessee
