If you live somewhere that gets colder (and is windy) than 35F these gloves alone will NOT be warm.

I wore them all winter (and on my winter trip abroad) with another pair of huge knit gloves, and there were some days I was afraid I might get frostbite.

If you are keeping your hands in your pockets, they're ok, but for bike riding or doing anything outside beyond walking leisurely these won't be enough.  Also, gloves being made from a knit is a terrible idea because it will get caught on anything with small hooks, like velcro.
