this is the beanie i use for everyday riding under my helmet. it is warm enough but it is not to warm that you sweat insanely. i find that because it has a more fitted style that it is better for wearing under the helmet, also i wear it normally sometimes and its great for something to keep you warm. It is 95% acrylic so it isn't very waterproof infact it does get pretty wet but wearing it skiing is no problem it isn't nearly as bad as some cotton toques i have had. overall this is a great toque!
