I own/run a guesthouse and am using these wine glasses for outdoor use. My guests have many outdoor options like the hotub, the gas firepit, the grill, outdoor dining table, zero gravity chairs, the pool, hammocks under a tree, and hammock chairs under the pergala. It is therefore very important that I also have good options for eating and drinking outside. These unbreakable glassed are perfect for that. They do get a little warm at the gas firepit and could possibly melt, so I tell my guests to be careful. The stem could be a little stiffer? It can bend, but it goes right back. Something to be aware of if you are trying to carry multiple full glasses. Don't use pan scrubbers on these as they will scratch and/or become cloudy. I hand wash mine because they are too tall for the top rack and are not recommended for the bottom rack of the dishwasher.
