The magnetic sleeve that keeps your water bottle off the gym floor.

The BLAUBECK Magnetic Water Bottle Sleeve wraps around your bottle and uses four strong N52 magnets to attach it to any steel gym equipment: squat racks, benches, treadmill frames, and lockers. Your bottle stays within arm's reach between sets instead of rolling across the floor. A large front pocket holds plus-sized phones, and a zippered compartment keeps cards, cash, and small essentials secure while you train.

What it solves

Your bottle keeps ending up on the floor: Clip it to the rack or machine you're already using. No more kicked-over bottles or hunting for a flat surface.
Your pockets are full at the gym: Phone, keys, cards, and cash travel with your bottle in one unit, off the floor and off the equipment.
You move between machines: Pull the bottle off, walk to the next station, snap it back on. Everything you carry moves with you.

Build details

Four N52 magnets attach to ferrous steel surfaces like squat racks, benches, and lockers. Not compatible with aluminum, plastic, or rubber-coated equipment.

Anti-slip neoprene with an inner rubber band keeps the sleeve from sliding, and the hook-and-loop closure adjusts to your bottle's exact size.
Large front pocket fits phones up to 6.9 inches including the iPhone 17 Pro Max, plus a zippered pocket for cards and cash and a side loop for keys.
