There are plenty of signs that summer has transitioned into fall.

The calendar telling you so is a big one. Same goes for that slight chill in the evening and a proliferation of Oktoberfest beers at your local bar.

We choose to ignore all of those things and wait for a single harbinger to alert us to autumn's arrival: the henley.

So, now that this versatile workhorse of a long-sleeve shirt is beginning to make its appearance on upper bodies everywhere, we're confident to share that, yes, fall is officially here. And below are 10 of the finest henleys around. Wear them, layer them, love them.
