My Pool and Beach must have is this lanyard case for my phone! It has been such a great thing in my life. You can use your phone while it is in the case, you’re safe from any splashes or sand piles, and it’s so handy to have your phone right around your neck so you know nobody will grab it off of your towel at the beach either. It’s less than $10 on Amazon, and comes in a few other colors like black, green and blue.
Trust me, this is an investment that is worthwhile, haha. We spend most of our summer days poolside, and I’ve been involved in many phone accidents. I’ve had a two week old phone drop into the pool and a three day old phone shatter on the sidewalk near the pool. I’ve had a phone stepped on and shattered while inside a diaper bag, and I’ve found my phone wet after kids piled wet stuff on top of it in my bag. I bought this case last Spring, and it worked great for me all summer.
Now I’m not going to dive into the pool with my phone, I always set it on a table- but you supposedly can dive in with it too. Happy Pool Days!
