· A stick of SPF sunblock: No, we're not talking about toting around a tube of greasy cream that you must then embarrassingly rub on your arms and face while out for a walk or alfresco lunch. Get thee to a drugstore and check out their sunscreeen section; Duane Reades in NYC sell a small stick (looks like a doublewide chapstick) of SPF 30 sunscreen, or just check out all these sunblock sticks on Drugstore.com. Just give your skin a quick swipe and you're good to go.
· Sunglasses that make you think "ooh, I look good." The best coolest sunglasses we own cost $5 and were an impulse buy on a day we felt especially awesome. Now they're a permanent fixture in our bag as well as on our face. If you haven't updated your sunglasses in the last two years, it's time. They don't need to be expensive, but do think forward in terms of design. Think classic Persol frame shapes or anything new from Warby Parker.
· Wet wipes. They're not just for children. We started carrying tiny packs of wet wipes in Thailand, when the humidity forced us to do wipe-downs when entering any respectable establishment. Now we can't live without them. Wet wipes come to the rescue during sweaty times, smelly times and unexpected food truck mealtimes. Also if you've applied some of the sunblock stick stuff and want to quickly clean it off.
