WALLFID 2PCS Thermal Phone Case Bag with and Keyring,Prevent Phone from Dropping Battery Due to Cold Weather,for 6.7 inches Phones and Power Banks and Wireless Headphones Black(Black)

Keeps cell phone insulated from the weather, xlarge case was great for a Samsung S23, including Otter box, highly recommended

I bought these to take to the beach in FL. They didn’t work for me. Maybe if you put your phone inside them and don’t take it out, but if your phone is hot already from use, putting it in the bag just keeps it hot.

I bought this just to try and was pleasantly surprised at how much I love this product. It's perfect for an outdoor event during winter; especially snowmobiling when the cold takes the biggest toll on my phone. I can also fit my license, credit card, cash, a chapstick, and small pack of gum inside. I clip a lanyard to the loop attached to the item and put it around my neck to keep it safely inside my jack when I'm on the trails.

well made, perfectly fits i phone pro max will work in cold and hot

These look surprisingly well built nice tight seams but it still wont keep the phone cool enough. I placed it in my center console while at work and I still had overtemp warnings when i took it out..this was on a upper 80’s day.. I put a thermometer in one and it was getting to 110*F on sub 90* days.. so this definitely does not work as advertised..it may work in the cold and os probably good for protecting from physical damage but no good against a hot car

Stiffer than I expected and Works more for cold weather than hot weather in my opinion.

The product is large and would fit most, if not all, phones. Quality is good. Cons is that it didn’t keep my phone nearly as cool as I had hoped. Phone didn’t overheat or anything but it was much hotter than I thought it would be. Overall it’s average at keeping your phone cool.

I guess only to be used in cold climates...have taken to beach, left my cell in the case inside a beach bag and my cell gets very warm, the insulation heats up my cell...not what I expected
