Dry Shake Accident

I found one way to keep the inside of my slingpack dry. Leave some dry shake partially open. Your pack will stay annoyingly dry for what seems like an eternity. I used to like dry shake and feel it was God's gift to fishermen. Now every time I reach in my pack to get something my hand feels desiccated. I can't do anything else until I wet it. I haven't dunked the whole slingpack in the water yet but the idea is very tempting. Just a friendly reminder to make sure whatever you use to keep your flies dry stays secure or outside of your pack.
