Hands-free hydration is the way to go! This carrier bag is specially designed to snugly fit your 40oz Stanley Quencher tumbler (the ones with the handle, like the H2.0 FlowState or Adventure Quencher). It's made of flexible, padded neoprene that protects your cup and provides some insulation. The best part? The adjustable, detachable shoulder strap lets you wear it crossbody, so your hands are totally free for walking the dog, hiking, shopping, or chasing kids. It even has TWO front zippered pockets – one big enough for your phone and a smaller one for cards or keys. As a bonus, it includes a little cover to keep the straw clean! You can also use the attached 'pearls' handle to carry it by hand if you prefer. It fits right into your car's cup holder even while in the bag. Perfect for any on-the-go activity: gym, commute, travel, festivals, you name it. A must-have accessory for Stanley cup lovers who value convenience. (Heads up: it might have a slight new-material smell at first, but it'll air out quickly.)
