WHO, WHAT, WEARABLE Bellabeat Leaf One of the most feminine (and fetching) wearables on the market, the Bellabeat Leaf is an activity and health tracker hiding inside a pretty leaf-shaped wood-and-silver clip. The device, which can be worn on a skinny double-tour leather bracelet, strung from a thin silver chain, or clipped to a shirt or waistband, monitors a user’s fitness and sleep as well as a woman’s monthly cycle. What we liked: The Leaf is so good-looking, we were always getting asked about it. And every aspect, from the wood to the leather bracelet, feels well made.  What we didn’t like: The device itself is on the thick side—no doubt by necessity. And hooking it onto the leather bracelet takes a little practice. Best features: Its mission: The Leaf promotes a life of healthy habits, such as proper sleep, power walks, and meditative breathing.
