The Best Coolers
Coleman 9-Can Cooler
Small and light enough to carry on a hike, with a hard plastic liner that slips out for washing (and keeps your PB&J from getting crushed). Sized just right to hold drinks and snacks for four or a full lunch for two.
To buy: $13, coleman.com.
So maybe you can’t change your health overnight. But you can get a head start.
