Staying cool isn’t always easy at a summer fest. Our tip? Pack a mini bottle of evian Mineral Water Spray for an instant dose of hydration. Don’t worry, we can promise your makeup will stay intact. Speaking of beating the heat, if you’re worried about sweat getting the best of you, a travel size perfume spray like the addictive Yves Saint Laurent Black Opium, always does the trick. And since just like a festival lineup, we always save the best for last, don’t even think about heading to the concert grounds without some SPF. Shisiedo Sun Protection Stick makes applying (and reapplying!) sunscreen easier than ever with a portable, roll-on formula that blends easily into skin.
