I love these quarter-zip pullovers. I bought this one as a gift, but I personally own two others myself, which should say a lot. They’re comfortable, lightweight, and extremely versatile. I wear mine for golf, casual office days, and layered when it’s cooler out—they pair well with just about anything. For the price point, they really can’t be beat. The look and feel are comparable to options that cost significantly more. Great value, great performance, and a sharp, clean style. I’ll likely keep buying more.
