This is a nicely comprehensive list of available covers for the Amazon Kindle Paperwhite. The lightweight but sturdy ones from Huasiru and Ayotu make nice gifts and feel good in the hand.
But if you’re willing to pay with a few more ounces of weight, there’s another option. The cover that I use for my Amazon Kindle Voyage and have used for Paperwhites is one of the many tooled leather designs made by Oberon Design in California. They are beautiful and give a touch of luxury to your day. Highly recommended if you spend as much time with your Kindle as I do.
