Upgrade

If it’s time to retire that old, banged up water bottle, here’s your replacement. The .75-liter VIVA is made of light, tough, BPA-free polypropylene, and comes with a versatile top that lets you choose between a dribble-free, 1-inch opening or a UV-wand-compatible 2-inch one. The tall, narrow shape makes it easy to slip into tight pack pockets. $20; 4.9 oz.; mysigg.com
