We've been fans of SIGG water bottles for ages, especially since our originals are still holding up to our daily abuse. Which doesn't mean we're not in love with their new line, including this Active Top Pink ($29)! The bottles boast their signature BPA-free aluminum siding, but integrate a new top outfitted with a pressure-relief valve system with four different settings. Keep yours closed or open, or turn it to "air" if you're drinking something carbonated. Move the top to the "clean" setting and it pops apart for easy rinsing. The straw is sturdy, too, and won't leak, even if it's tipped over or jostled to the bottom of your bag.
