Just from memory...this is what's in my vest.

2 mouth calls
2 box calls
insect repellant
clippers
3 3.5 shells for NWTF Browning 10 ga
GPS
Book
gloves
hat/face mask
flashlight
compass
cigarette lighter (actually just recently quit after 30+ years...hope it sticks. Thank God for Nicorette gum)
chalk
soon to be gobbling tube (just bought a few days ago as turkey's where I'm hunting aren't gobbling good and I want to try and get them stirred up)

I think that's it!
