For sub zero temperatures, these make a great outer layer without bulk many other gloves have. Whilst I am female I did buy the large size due to my non delicate hands and the fact I was wearing glove liners also - worked out to be a great decision, although I would imagine most men doing the same thing would need to buy extra large. The picture advertising these make them look quite big and loose, they're actually quite snug with liners without being too hot. This product worked out to be fantastic value when you compare to gloves specifically designed for extreme cold.
