In my opinion, the best summer meal is one eaten in the sun (with a glass of rosé or white in hand). But when it comes to packing a picnic, there’s always the issue of cups: you’re doing a disservice to a nice bottle of wine if you’re sipping it from plastic tumblers, but your nicest glassware isn’t going to survive rattling around in a picnic basket. These BPA-free, unbreakable wine glasses are your answer. They’re made with a one-of-a-kind material that looks just like glass—my guests couldn’t even tell the difference!—but is virtually impossible to chip or crack. I definitely recommend stocking up on these for summer poolside drinking.
