I've been getting the best performance using a long sleave paddle shirt from Xcel Wetsuits (Ventx Model, www.xcelwetsuits.com
) and a pair of swim shorts with lots of sunscreen on legs or performance running tights (Under Armor) if it's a long run.
The running tights are working well; however, I only found one pair on sale and researching purchasing another one with similar attributes/features. Came across the Zhik's (www.zhik.com
) Hybrid line of sailing performance wear. It might be something you're looking for but I don't have personal experience with them. Someone on this forum who has might be able to chime in.
