They are very good gloves for use inside regular gloves. They are not suitable for use on their own in winter.

With these specific gloves, you can unlock your mobile screen and also write normally! The only thing you need to know is that they are gloves worn inside other gloves, whether knitted or leather.

Very honest gloves, as they appear in the photo, they fit well on the hand and keep you warm. Something important because many write that they don't warm you up, the gloves are thermally insulated and thin, they are not meant to warm you up, but to keep you temporarily warm.
They are ideal for exercise, light work, or if you go in and out of cold-hot environments, if you plan to go skiing or be outside in the cold for a long time, they are not suitable.

Even through thick gloves, it does not warm up enough. Maybe for less cold weather, but not for a harsh winter.

They are very good for thermal gloves and keep you warm, but when it is very cold (-5 to -10), they are not enough, you need to put something more

Quite warm. I wear them inside my mid-season motorcycle gloves and they become winter gloves. I also wear them on their own when I'm not driving and they do a very good job! I recommend them!
