Whether it’s the beach, out in the woods, or just a picnic at the park, there’s one thing a day outdoors has in common: a pack, bag, or case is always invaluable. The variety of bags available today means you’ll always have the perfect amount of space no matter where you’re going or what you’re doing. A duffel, for example, is perfect for traveling. It packs easily onto a plane or into a car and can be loaded with multiple days’ worth of clothes and other important gear. Both small and large backpacks make sure you’re well equipped for hikes and overnights, whether it’s loaded with just a first-aid kit and snacks or a tent and supplies and for a week. Beach bags fit a few towels and other water toys like snorkels and deflated beach balls—and some are even made of mesh to keep sand and water out. Speaking of, if you’re planning on getting out on the waves, a dry bag is an absolute must. Keep all of your valuables and electronics safe and sound without any fear of them getting wet—even if they happen to fall overboard. You can even find mesh containers and stuff sacks that are perfect for bagging up dirty laundry or trash around the campsite.
