5Oaks Thermal Phone Case Smart-Phone Pouch Cellphone Case Cover Bags for iPhone X, 8,8 Plus, 7, 7 Plus, 6,Samsung Galaxy

Used this while hiking in the mountains during the winter in Colorado. 1F - 40F. If you are going hard and sweating it keeps the phone dry. If you are sitting for a couple hours where it’s really cold it keeps the phone insulated. I noticed a difference in battery performance when I forgot it. It can clip it onto my belt loop and I tuck it into my pocket. Cool product

I was experiencing an issue where I’d go on my walks in the winter and whenever I tried to use my phone when I returned home, it would be really slow and glitchy for the first 10-15 minutes from the cold. But this thing solves my issue! Even in 19 degree weather with wind chill of 10, my phone stayed pretty warm. Definitely worth it.

It fits my phone great!(note 9). Protects from over heating when I'm outside or in the sauna which is why I got it. I removed a star because I was sent the wrong color from what I ordered.

Cute little phone protector bag I bought it for when we go to the shore. It gets so hot at the beach. Also, it makes a great little safe bag for your phone in your purse. Definitely recommend it.

I got this to keep my phone from getting cold while hiking during the winter and thus draining its charge. Starting with a fully charged phone and returning 1-2 hours later without using or exposing the phone, the charge has been nearly fully drained. So this pouch doesn't seem to work as I thought it should.

Fit's iphone 11 perfect with a case and pop socket. However the thermal pouch isn't great to prevent it from getting cold. My phone still turns on with 100% battery. But this was also used when the temperatures dropped from 0 to -25 at most.

Use whenever I take a walk or garden

Bought to keep cell phone from overheating. Had phone in bag in pocket on 100 degree days and no issues. Haven't used yet in cold weather but would expect to keep warm.
