If you soon find yourself gawking at foliage and noticing a chill in the evening air, there's a good chance that fall has descended upon you.
But there's only one way to know for sure.
Look to your left, then to your right. If everyone around you is swathed in a cozy henley, then you can confirm that it is, in fact, fall.
Because nothing—not football season, falling leaves nor calendars—signals the start of fall quite like this pullover shirt with its buttoned placket.
So to assist you with this season's most important attire, we've collected 10 great henleys and placed them below. Wear them on their own, or enlist them to layer over or under basically anything else you own as temperatures begin to drop.
