Stanley cup fans, this is a game-changer! This isn't just a sleeve; it's a whole carrier system for your beloved 30oz or 40oz Stanley Quencher H2.0 or Adventure tumbler. Made from premium neoprene (like a wetsuit material), it does a few awesome things. First, it protects your cup. No more annoying clanging on tables, no more scratches or dings on the bottom or sides. The neoprene cushions it perfectly. Second, it's a carrier. It comes with a removable, adjustable padded shoulder strap that you can set anywhere from 27.5 to 50 inches. Now you can be hands-free while shopping, hiking, or at the gym. Third, it has storage! There are two front pockets big enough for your phone, keys, cards, and some cash. They even include a straw cover to keep dust out of your drink and a carabiner clip for keys. It's a snug, custom fit designed specifically for Stanley's shape, and it still lets your cup fit in a car cupholder. Perfect for walks, commuting, camping, sports events, or just daily use. It even comes in a cute 'Dabria pink' and is a US patented product. A must-have accessory and a fantastic gift for any Stanley fan. (Little note: It might have a slight smell when new from packaging, but just air it out for a few hours).
