This jacket has excellent wind resistance and water resistance. Its not quite a gortex, but good enough for if there is a slight down pour. Fleece lining on the insider keeps you warm. The only jacket I take backpacking, at night I just flip it inside out to get a soft pillow. Mesh on one side of the pockets allows for ventilation into the jacket.
The only bad thing about this jacket is that if it is really cold or windy out, and you have the hands in the pockets, some cold air seeps in because of the ventilation. So you loose a little heat. So just close the pockets and wear some gloves
