I have three canine athletes that do multiple sports and outdoor activities. I currently have two Chillybuddy Canine Cooling Jackets (two boys share since they are similar in size). These cooling jackets are by far the easiest jackets to use. Dry or wet, they will most certainly keep your athlete comfortable after their agility run, flyball run, bikejoring tour, and general hiking during warm weather. I have had other brands of cooling coats before and have either sold or traded them away. I will ONLY use this jacket for my boys. My boys love wearing these jackets, they are light-weight and very flexible to wear while in their kennels waiting for their next run. I HIGHLY recommend these jackets for your athletes.
