Sure, a half-zip sweater has some very specific cultural associations — but there’s a reason you see them in dozens at farmer’s markets and on youth soccer sidelines. It’s one of the best weekend sweaters out there. A little sporty, a little retro, not too dressed-up or fussy, and literally designed for easy layering. This one is knit from cotton with a touch of cashmere in the mix. It's lightweight enough for transition weather but substantial enough for true fall.
