i'm entering april's naga tournament and read in the rules that competitors are to wear shorts with no pockets. in class i normally wear plain boardshorts with a small cargo pocket, and one pair i have has a 'hidden' pocket on the side with a zipper. will those work? for anyone who's entered in the past, are they strict on this rule? was considering getting a pair of closed seam sprawls or something similar, although i'd like to wear what i'm used to if that's an option.
