Question: Are these single or double walled? Thanks, Steve
Document: OVer all the cups are sturdy, but I was disappointed that after one wash, one of the cups had rust at the bottom of the interior where the liquid goes! It's been several weeks and we've used the other cups and haven't had that problem with the others, but it just makes me wonder about the cups themselves. THey are light weight. StainlessLUX 77317 Double walled Stainless Steel Drinking Glasses, 12-Ounce/1.5 Cup, Set of 4  are much better made.
They are also very easy to clean up.Thanks for making such a great product!
They are exactly what I wanted. My entirely family prefers these to plastic or even glasses, especially for water. Thanks!
My first impression of these cups:Ergonomically friendly, well built, and lightweight (single cup).These are the perfect stainless steel cups for car camping or picnics with the family because they're bomb proof, easy to clean, and compact when all 5 are stacked together.
One other thing to remember is this cup is it&#8217;s a single wall cup, and its stainless steel. Which translates into, if you put something hot in the cup, your cup is going to be HOT to the touch.Over all this is one of the nicest quality single wall, stainless camping cups I have used.
These Fox Outfitters cups are great. They came surprisingly well packaged, with tissue and cardboard separating each cup to prevent scratching or suction during shipping, and I didn&#8217;t have a problem pulling the cups apart like someone did in a previous review. There is a single inconspicuous, very stylish logo on each cup.
I think they are an excellent product that would serve well anyone who wants an indestructible vessel for any application.Thanks for reading, and check out TheGearWhores.com for more product testing and reviews in the future!
They are single wall stainless steel construction, one can actually put 2 cups (16oz) of liquid in them, they don't leak, I doubt we will ever break or seriously damage them and they are quite stable (don't tip over as easily as I would have expected). Since they are single wall stainless steel when filled with hot liquid they will get hot. When filled with cold liquid they will get cold and sweat when the humidity is high enough.
The bottom of the cup lists its capacity (1 pint/16 oz/473 mL). It may have been helpful for Fox Outfitters to include measurements on the inside of the cup so that they could double as measuring cups, but that would probably take away from the overall visual appeal and simplicity of the look.
very sturdy, no metallic taste( have used for iced coffee, ipas, stouts, and water) , and my package came with 6 cups
Answer: yes
