The Dartmouth has been revised for the new season. Lighter breathable fabric all over makes it easier to wear, shorter zip is more comfortable. Neoprene seals are great for comfort as well. Two colourways, I have plenty of the blue but limited number of black/red. The sizes go from small to xxl, but we always do well with mb as it has the width but normal height, so great for the mature man with spreading waistline.
