We use backpacks. Each kid has their own. The two-year-old is even accustomed to wearing hers on hikes, but when we aren’t going at a leisurely pace she goes in an Ergo. The older kids have bladders built into their bags, but mine is just the plain old backpack I’ve had since college.
We have very basic supplies:
first aid kit, sunscreen, bug spray, extra socks (more clothing depending on the person), cash, a contact list for emergencies, multi-tool (only the kids responsible enough to be trusted), lighter (again depends on the kid), emergency blanket, hat, gloves, whistle, poncho, compass, and snacks
If we will be further than 15-20 miles away from home we pack more, but that’s it for a normal day.
We wear tennis shoes or hiking shoes as our everyday shoes and we favor jeans, t-shirts and fleeces/sweatshirts.
My husband has a much more extensive GHB due to his work.
