Glass and pools do not mix. My landlord's warning about this was unnecessary...but appreciated. Beyond the obvious risk of bare feet and pieces of broken glass I am the guy who always finds the last shard. No matter the toweling, mopping, vacuuming, down-on-your-belly-flashlight-searching, I discover one last piece, sometimes weeks later, embedded in my foot.
I resisted buying "glasses" made of synthetics because I feared the wine wouldn't taste, or smell, the way it should. However, serving wine for another summer in plastic Mardi Gras cups was even less appealing and I caved.
Govino got my nod for a test drive and now my recommendation! They are shatterproof, though I do think you could break them with a little effort, and did not smell of plastic even immediately out of the package. Impressive. While I maintain a dislike of stemless wine glasses, these are ideal for wine drinking anywhere you don't want glass. The pictures on the home page show some Bocce balls in the background which appeals for my Maine visits where we play cross-country Bocce - no groomed courts for us thanks.
They do give a little if you press them but they are sturdy and I never feared they would collapse or fall over. They can not be packed flat and they do not nest inside one another but a little jostling won't break them and having them at a pool is fine. A friend recommended avoiding the dishwasher as they will warp a bit from the heat, I took him at his word and did not experiment.
I am thrilled to be able to drink wine pool-side out of a proper-ish wine "glass" but these would be great for camping, the beach, picnics, etc. Thanks govino, these are winners.
Govino also makes decanters, flutes and now a beer "glass" too. There is also a "cocktail glass" which is nearly indistinguishable from the wine version - a little shorter and with less capacity but I would opt for the wine version and stick with it.
