Just curious what others consider essential in their upland vest and why. I hunt in western Minnesota so I'm seldom more than a 30-45 minute walk to my vehicle and space is wide open so no need for a compass. My vehicle has a 1st aid kit for dogs and humans, a skunk kit and more water.
Here is my list
1 liter water bottle with squirter top
plastic bag with baby wipes
black electrician tape
2' slip lead
Headband type ear warmer that goes over a ball cap (switch out to face mask as weather cools)
Cell phone (either off or on vibrate)
My transmitter and whistle are on lanyards and I generally carry a swiss army knife too.
