Needed a heavier-than-usual sweatshirt for playing golf. This pullover is a tad heavier weight than normal sweatshirts, has the quarter-zip for easy on and off over a baseball hat, and loose enough around the hips to allow for body turn during the golf swing. This pullover does NOT allow any cold air seepage through the cloth (as some more porous materials do), and the cord-drawn bottom allows you to decide how tight/loose you want it. I bought three of these for those colder days of golf, as I play all winter. They are a nice alternative to a coat or additional layers (baselayer/thermal, turtle neck, and then this pullover are all that's needed...no bulky coat). Excellent product!
