This stylish pair of jeans not only cares about how it fits you but also keeps your smartphone battery charged.

Joe's Jeans launched campaign #HELLO jeans in August and these jeans immediately became a furor. Equipped with small phone-charging, the jeans "charges" device while it in a right back pocket.

"The on-the-go charging concept had been in the back of our minds ever since mobile devices became so popular," Joe's Jeans founder and creative director Joe Dahan said.

Jeans are available in various designs for women and men, special #hello slim battery can be bought for $49 on joesjeans.com.
