At less than 12 pounds, the Quinny Yezz ($280) will be one of the lightest — and most unique-looking — strollers on the market when it hits US stores in March. The backpack-like folding frame folds in on itself, creating an almost flat fold. Though the stroller doesn't recline and won't have a storage basket, its wheels — which bear a strong resemblance to skateboard wheels — create an unbelievably smooth ride.
