I put some calls and strikers in the pocketsand see no issues. Pots fit fine in the pockets and a box call will fit in the long front pouch with the handle sticking out a small bit. My standard setup now is a purr pot, ghost cut diaphragm, and a wing-bone, so this is overkill for me, but gives more room for binos, range finder, water bottle, and tote with room to spare. I did have it loaded up with boxes of ammo, a bunch of chokes, rangefinder, and other gear while shooting yesterday which is much heavier than almost anyone would carry hunting and it was fine even with all that. This is definitely one of the better options and especially at this price.
