"Purchased one of these FJ HydroLite™ Short Sleeve Rain Shirts yesterday and threw it in my bag this morning. Always carry a rain suit just in case. As we approached hole #8 today the thunder cracked and the sky opened and here came the rain. Thank goodness for my new rain shirt. Kept me dry through the next four holes we played. Did not hinder my swing in any way. One bogey and three pars, even with the rain. Would highly recommend everyone having a lightweight rain shirt in their bag this time of year. You don't want to let a little rain stop you. Thank you FootJoy....cz : )"
