All of your activities are not the same, but what will remain consistent, is the second skin your ColdPruf Base Layer will give you. Just as raking leaves, camping, or having a good old snowball fight, take effect, you can know safely that you will NOT be weighed down by ColdPruf&';s light design or constricted by its stretching material. ColdPruf will let you get all your outside chores done while maintaining your warmth and comfortability.
