FrostProof™ Thermal Phone Pouch

Why Skiers And Hikers Are Zipping Their Phones Into This $19.95 Puffer Pouch

Cold weather drains phone batteries fast. That’s why your phone dies at 40% on the slopes. FrostProof™ wraps it in a quilted puffer layer that blocks the wind and holds onto warmth, so your phone is ready when you need it.

FrostProof™ is a lightweight quilted thermal pouch with a soft padded interior, a drawstring toggle to seal out drafts, and a shiny iridescent finish. It fits most smartphones and comes in 5 colors.

A Winter Jacket For Your Phone.

You wear a puffer to stay warm, so give your phone one too. The quilted padding creates an insulating barrier against freezing wind, and the drawstring cinches tight to keep cold drafts out.

Slips In Your Pocket. Weighs Nothing.

It’s light enough that you won’t notice it in your coat or backpack, and the padding adds a little extra protection against bumps too. It’s perfect for ski trips, winter hikes, football games, and long dog walks in the cold.
