How do you improve on the awesome drinking utility of the mason jar? Give it a better-than-Starbucks wrapper and a handle. The Holdster Mason Jar Mug ($20) slips onto standard wide-mouth jars, cladding them in leather and keeping the heat — or cold — away from your hand. Available in cross-stitch or riveted styles, and with or without a looped leather handle, they're a great way to add a touch of class to this traditional vessel. Combine with a Cuppow to create the ultimate farmland-esque travel mug.
