Not warm at all and run way small.
- Familiarity: I've used it several times
I bought these because they were said to keep hands warm down to somewhere around 25-35 degrees (can't remember the specific number off the top of my head). However, when wearing in 35 degree weather I felt they made my hands colder than going without them. It was almost as if it let cold air in and trapped it there.
On top of that, the XL fits more like a L, possibly even a bigger M.
I really wanted to like these gloves as I really liked the way the fingers could fold open for precision hand usage. The quality of the glove looks and seems nice, and I'm sure it'd be a great glove in slightly less cold of weather. But just have nothing positive to say otherwise.
Ultimately I ended up just taking my gloves off and not wearing them at all the rest of the day that I was going to depend on them.
