Mossy Oak Turkey Vest for Sale. I've used this for the past few seasons and it has served me well. Plenty of pockets for all of your calls and field gear. Has the built in seat cushion and rear storage pouch for decoys. $35 shipped.

What size?
Correction, it's S/M, however I wear a large shirt normally (6'1 200lbs) and this was very comfortable. The adjustable straps allow it to fit many different sizes.
