If you need to remind yourself about the cycle of life while keeping your fingers warm this fall, I highly recommend these predator-and-prey mittens. Each pair includes one predator and one soon-to-be-lunch.
You've got your frog vs. fly mitten pair, lion vs. gazelle, and whale vs. fish. I love the details here, like the fly wings spread across the top of your hand, and the fish smoochy-mouth at the ends of your fingers. Teach people at the bus stop about the way ecosystems work just by waving your hands. They're $26 per pair, which is a small price to pay to get a chance to wear a biology lesson on your hands all season.
