Our Fourth of July plans include drinking mint juleps, eating BBQ, and spending at least 12 continuous hours in the sun. That means we are going to need several sunscreen touchups throughout the day. So, we're stocking our weekender bag with a few miniature SPF products. These travel-size sunscreens will fit in the smallest cross-body bag, right next to your red lipstick and blotting papers. Plus, TSA won't get upset if you have to stash them in your carry on. Whether you're planning to ride bikes on the boardwalk or mingle at a rooftop soiree, you'll be prepared to follow the two-hour touchup rule. There are even tiny SPF products that work over your makeup! Leave the big bottles of sunscreen in your beach bag and travel light this holiday weekend.
