The water bottle sleeve with a magnetic phone holder built in.

The BLAUBECK Magnetic Water Bottle Phone Holder is a stretchable neoprene sleeve combined with an integrated magnetic phone mount. Wraps any standard gym water bottle, Hydro Flask, Stanley, or Nalgene. Magnetic mount snaps your iPhone or Android phone to your water bottle at eye level during workouts. Pull off the bottle, the mount comes with you.

What it solves

Your phone keeps ending up on the gym floor: Mount it to the water bottle you're already carrying. No extra accessories, no separate clip, no wall to lean against.
You hate juggling phone and water: One unit handles both. Drink, reposition, watch the next set, all without setting your phone down.
You travel between gym machines: Carry your phone with you naturally, attached to the bottle that already moves with you between exercises.

Frequently Asked Questions

The BLAUBECK Magnetic Water Bottle Phone Holder combines a stretchable water bottle sleeve with a built-in magnetic phone holder.

It is designed specifically for gym use where you want your phone visible without putting it on gym equipment.

The sleeve is made from stretchy, flexible material that accommodates a wide range of water bottle sizes and shapes — from standard gym bottles to wide-mouth Hydro Flasks and Stanley cups. The elastic design stretches to fit and holds securely without sliding down during workouts.

Yes. The magnetic phone holder component works with MagSafe iPhones directly. Android phones and non-MagSafe iPhones can use the included metal magnetic ring, which attaches once to your phone or case for a strong magnetic connection. All modern smartphone sizes are supported.
