Carrying multiple bags is for donkeys, sherpas, and women named Mary Bags who wear several pairs of support stockings at once. This versatile bag functions as a single duffel or three separate bags that can be zipped apart or together (with heavy duty zips) as your needs demand. Pack your gym gear in one bag, dancing shoes for party after work in another bag, and change of clothes for tomorrow in an overnight bag (you hussy!), and then just grab which section you need. Smarty bags.

My brother and his wife just got back from a three-week trip to Australia. I told them––as everyone told them––that they didn't need to pack much, but they packed much, waaay too much, and paid the price, the $800 price, to have their overweight bag shipped home separately. For the same price, he could have bought three nifty Timbuk2 Checkpoint bags. They have tons of compartments for smart packing, skate board wheels for speedy airport-trekking, a removable pouch for liquids and gels, handles on all sides, and even secret pouches for valuables. Available in medium and large.

I haven't used a plastic bag in ages. I'm not telling you this so you'll applaud or praise me (pause here for applause and praise), but rather to explain why I've amassed quite a collection of reusable bags. Most of them advertise the stores I shop at and some of them advertise how selfless I am to carry an ugly bag so the polar bears don't have to find new digs and possibly shave. RuMe's (roomy) reusable bags are designed to mimic an old-fashioned paper bag, with squared sides and a bottom to easily fit anything. The roomy handles allow for bulky jackets or sweaters and the cool designs allow you to shop and save the world in style.
