They do put liners in the gloves that we have for other than work things they are super warm but a little bulky for anything other than keeping you hands warm. The thing I like about these is that they fit. I have big hands and cant find gloves that let me spread my thumbs away from the rest of my hand without restriction when they make these the make a print of my hands on paper and use that as a template. When the put the liners in they make them just a tad bigger. They make them for other companies I thought that was weird but if it makes money thats what they are in it for.
