Yeti has improved its classic Rambler Mug! It's still stainless steel, it's still stackable, but now it has the DuraSip ceramic lining! This ceramic lining is fused to the 18/8 stainless steel, making it tough enough to take a tumble and come through without cracking. The ceramic inside is resistant to coffee stains and easy to clean. As before, the Rambler Mug is made of 18/8 stainless steel, with double-wall vacuum insulation, and a welded handle. The 14 oz. size makes it large enough to double as a camp bowl. Yeti Rambler 14 oz.
