So I bought these not really knowing if a glove could make my hands feel cold when its hot out. Too my amazement, they totally do. I wore these on the lower glacier for two Denali expeditions and when it was brutal sunny and I was wearing a buff over my face, sun hoody, shades and everything, these gloves were on and occasionally my hands felt cold! It was kind of bizarre at first. They are ripping and wearing out after about 10-14 days of heavy use which is a bummer, but most liners don't last long. I do enjoy the fact they work with a touchscreen most of the time. I probably wouldn't use these for anything else other than walking on a glacier when the death star is trying to kill me with its rays.
