Timbuk2 Steve Sleeve

Ever since the unveiling of the MacBook Air, there's been clamoring for cases that mimic that now legendary manilla envelope. The Timbuk2 Steve Sleeve ($50) is one of the best we've seen yet, made from PET (100% recycled plastic bottles), and featuring a biodegradable TPU liner, welded seams, a recyclable polyester button, and a perfect fit. It's as green as the Air it holds. [Thanks, Paul]
