What is the interior surface made of?

I'm not home now, so I can't check, but it is NOT a no-stick surface and it shouldn't rust.

I gave it as a gift. They say it has some sort of enamel like coating. Not sure what but they aren't concerned it is going to rust out or anything. Don't know if that helps- but they say they love it.

It's an enamel, non-stick coating. Haven't had any problems with it-used it for about 2 months.

The interior is normal. Seal seamed nylon with coating. Closing the bag is easy, just like a SeaLine dry bag closure. Just make sure to squeeze out the air as you seal it. Great bag for light backpacking and bike commute

The interior is not bare stainless steel, it has a gray color coating film on top of stainless steel. However, I don't know what kind of material this coating layer is. You may google if you want to figure it out.

The Interior is Nylon. It's not a soft material, but I haven't had any issue with it scratching or marring the finish of either of the pistols I use it with.

Not sure what is inside. It feels like a heavy gel. We have had it for about 6 months and use it almost everyday. So far it has held up perfectly and it is very comfortable. We take it out of the tub and it sits on one of the steps to the tub when not in use.

The interior is not coated with non-stick. The interior of our toaster ovens are made of galvanized or aluminized steel.

The inside is plain stainless steel, highly polished. I think that is preferable to any coatings, as some coatings carry potential health risks. It also means it is remarkably easy to clean because you can use a bottle brush without worrying about tearing a coating. This bottle keeps things cold forever, and keeps them hot nearly as long. LIterally the best insulation I have ever experienced.

The inside is felt, so there is no metal contacting the surface of the machine. I have had no issues with scratches.

It is the same material inside as it is outside. This is my second one I really enjoy it.

The interior is not smooth like polished marble. It is just a natural finish like stone, it does not feel like sand paper,The roughness to it is very slight. It works well.

The inside is a non-stick. I sent it back because they had a warning about how it creates toxic fumes at high heat.

Inside I believe. Its a fabric case though so the difference between inside and outside dimension is marginal. Especially since fabric can stretch a little bit

yes it is, the inside is made from hard plastic, and the outside is made from a nylon canvas material.

The inside surface isn't like sandpaper nor is it rough. But, it also isn't like glass. When you fell the inside you can fell the texture/grain. If there is such a thing as grain in granite.

Interior is stainless as well. I think they are referring to the aesthetics of stainless as compared to plastic or glass.

It is made out of fiberglass, which stands up well to the environment outside, but is very difficult to keep clean. Lots of nooks and crannies in the (unfinished) fiberglass interior and if you get mold in there, you'll never get it out.

Can't tell about the internal parts, but everything on the outside is metal and it is fabulous. We just ordered two more!!
