Hi all-

I'm getting all like scientific and stuff about training and I downloaded a speedometer app for my iPhone so that I can use it to track paddling efficiency and effort more accurately.

I have a nasty SealLine clear dry bag that's like a big unreasonably heavyweight ziploc bag, but it's nearly impossible to close, which makes it nearly impossible to tell if it's closed. I'm thinking of getting a dry case for my phone. It needs to be completely dry because I'd like to be able to roll to cool off. Does anyone have any experience with using them in a kayaking environment?
