Even though it may be the dead of winter for those of us in the northern hemisphere, it’s not too early to think about those nice, warm summer days on the beach. For those days, you’ll probably want two things: tunes and hydration. If you’re one to kill two birds with one stone, you’re going to love the Beat Bottle.

The Beat Bottle is a silicone water bottle with a smartphone holder on the inside. This holder sports two functions: a theft deterrent and a sound amplifier. Since your phone is hidden inside the bottle, it’s better to leave it on your beach towel than your naked iPhone. Secondly, the bottom of the bottle is hollow and channels sound out, amplifying it in the process, making it perfect for those days away from power outlets. If you’re more of a solo music listener, you can also use this hollowed out space to run a headphone cable.

If you’d like to purchase a Beat Bottle, you can buy one here for $20.
