> BACKPACK STOOL
With all this extra gear, you'll need something to carry it around in, and many field archers use a combination bag/stool to have something to take a break on. Several archery manufacturers have produced these over the years, including Bohning and Lebrunet. You can find similar products in many fishing or hunting shops, so there's plenty to choose from. This Maximal backpack seems to be one of the last archery-specific products available, and should keep everything dry for days.
