1. NIID UNO 2 Backpack ($100) This fashionable bag wasn't designed to hold bottles and diapers, "but it may as well have been." It's made from a single piece of water-repellent fabric, and because it lies flat when unzipped, it doubles as a mobile changing station. Buy it at Amazon. 2. Removu K1 ($429) "This is a massive upgrade over the VHS shoulder-brick camcorder your dad brought home when you were a kid." A self-stabilizing one-handed camera that shoots "buttery-smooth" 4K video, it can turn even a novice into an "Oscar-worthy" cinematographer.
