You can always count on crewcuts to introduce you to the coolest lines for kids. Next up? Peters Mountain Works, a quirky Woodstock, NY-based outfit specializing in backpacks, luggage and accessories made of cordura, a durable woven nylon fabric with military gear roots. We got founder John Peters to increase the depth of his kids' backpacks just for us (to better accommodate a hefty haul of school books). Meanwhile, crewcuts designer Jenny Cooper, whose sons have been test-driving the bags to rave reviews, selected the colors herself.
