I just played a tournament in heavy rain. I had my goretex shoes on and my rain pants and some rain jacket, and a huklab umbrella(those are square), but the main problem was ...holding on to my disc!
It was kinda weird but my champion plastic had a much better grip than my star discs.
I brought enough towells but I still had a hard time drying off my hands or discs.
A few people played with golf gloves or something similar. To me that is absurd but maybe I am missing something here?
What Do You Do To Keep Your Hands Dry?
