When a former product designer for Apple (the company that managed to make computers adorable) turns her formidable talents to constructing the ultimate diaper bag, you know it's going to be good. And practical. And designed as if it's intended for use by actual human beings. The Cosmo Tote by Susanne Maddux lives up to our discriminating expectations, managing to be at once all-purpose, stylish and apparently indestructible. At this point, a cell-phone pocket is so done -- but an interior upright bottle holder? Now, that's a nice touch. Throw in padded shoulder straps, easy-access snap pockets (no loud, embarrassing Velcro, thank you very much) and the obligatory wipe-clean fabric (a sturdy canvas that looks prettier and more polished than your average vinyl), and it's obvious this tote was designed by an expert mom. $175 at SusanneMaddux.com.
