      Best Pouch Ever

      This is been great for my husband who works outside I actually bought two. That way I could put one inside the other and it works really well when he’s out in the woods cutting trees. Thank you very much!!!

      I needed something to keep my cellphone battery from dying in cold weather when I am hiking. This also protects my cellphone.

      What can I say, It protects my phone-heat,cold,and drops.


      Truly works in extreme heat and cold

      I hike all year round with a group of ladies and I stumbled across a Phoozy advertisement a couple years ago so bought one for me and one of my hiking friends. Our phones always shut down when it freezing out. They don’t now! And I bought one for my sister in San Antonio. She said her phone was always shutting down out at her pool. It doesn’t now! These truly work and save battery too! Kudos to the inventor!,
