Why? The only thing more important than keeping yourself warm in winter is keeping your child warm. What better fabric than cashmere to do it? Made from kids for kids, Banana Republic’s four-button hooded cardigan is woven out of Mongolian goat yarn—said to be the finest in the world. It feels thicker and more luxurious than most cashmere sweaters, at much less than the usual going rate of several hundred dollars, and, like the rest of Banana’s baby collection, it’s available only during the holiday season ($98 in sizes from zero to 24 months at select Banana Republic stores; 888-277-8953 or bananarepublic.com. After all, even kids can appreciate a little extra softness; it’ll remind them of their baby blanket.
