The perfect backyard drinking glass is the one that keeps your beer cold — and isn’t glass. Why? Because true glasses fall and shatter and little pieces of it end up in your lawn, making you the paranoid dad who makes his kids wear sandals in the backyard just in case for the rest of the season. We like these simple, BPA-free, shatter-proof glasses, which also have a gel between the layers that freezes to keep your drink frosty — and your lawn shard-free. Set of two.
