The large capacity 64 oz. Boss Growler from EcoVessel® keeps your favorite craft beer cold and fresh for up to 150 hours and hot coffee hot up to 24 hours with its double wall, 18/8 stainless steel vacuum insulated construction and copper lining. The dual-opening screw-top lid features a smaller opening with soft silicone lip for drinking comfort and a larger opening for easy cleaning and filling. The lid is lined with stainless steel inner for enhancing temperature retention and preventing drinks from touching plastic, and the TPR strap keeps the lid from getting lost and doubles as a carry handle. Fill the Boss Growler with chilled wine and fill the included snap-in steel infuser with fresh fruit to create a refreshing sangria. Through their partnership with 1% for the Planet, EcoVessel donates a minimum of 1% of all sales to various environmental nonprofits. FDA compliant and BPA Free.
