Say goodbye to warm drinks and spoiled beer. The 64 oz Bison Beer Growler keeps beer fresher, longer thanks to it's double-wall, vacuum insulated construction. Made from 18/8 stainless steel, it's powder coated and like all Bison Coolers products, it's guaranteed tough as nails. Fill up at lunch and enjoy ice cold beer that evening. Use it for water at the big game, iced tea on a road trip, coffee at hunting camp or margaritas out by the pool. The unique screw top is leak proof and also serves as a carrying handle.
