Make premium steakhouse-quality ribeyes, sirloins, and striploins from the comfort of your home with DryAgingBags™ Ribeye/Striploin. Our bags are made of a proprietary membrane engineered to allow airflow and release moisture from the meat, while blocking odors, germs, and other contaminants. This creates an ideal environment for safely dry aging whole cuts of beef in any modern home refrigerator. Impress your family and friends with "the best steak they've ever had" when you dry age sub-primal cuts for 15 to 50 days or longer to develop rich flavor and improved tenderness.
