Looks like you've got some rain coming next week, looking forward to hearing the sweat stories. On rainy days just throw the cell phone in a plastic bag anyways I guess.
I'd like to see the phone in a different place I'm constantly wondering about safest place for a phone in terms of it a) hurting you in a crash, b) not breaking in a crash, and c) being accessible in an emergency. This pack seems to fail all three categories. I've never had my phone in a place where all three of those would be the case, especially the access in an emergency where my mobility has been reduced. Maybe I'm overthinking this as a procrastination tool. Would love to see some sort of top-load firmly sealed velcro pocket on each shoulder blade... or maybe I need to just stop eating dirt.
