The protection of my phone is great piece of mind, especially in my golf bag. This size easily fits an iPhone with Popsocket attached.
The reason I bought it was the very hot summers in Arizona. It’s perfect for a hot vehicle, the hot sun, by the pool and on the lake.
When the phone ha# a protective case around it, it doesn’t fit inside the Phoozy.
Great case for the beach No sand gets on it and it doesn’t overheat
I run a lot and bought this to prevent the phone from overheating in the summer and getting too cold in the winter while it's in my hydration pack. Haven't been able to test winter yet, but so far so good for the summer - tested in my car on the passenger seat in broad sunlight, without Phoozy I got excessive heat warnings in minutes but with the case it didn't overheat. Only issue is that it's big, plenty of room for my Pixel 3a but makes it hard to fit in the pockets of my running skirt or hydration pack without some finagling. It's a tight fit in my pockets but does keep the phone from getting sweaty, or wet in the rain, so I do recommend it as long as you have room for it.
