A good pair of shorts never goes out of style. Outdoor Research makes a lot of great apparel for serious backcountry abuse, and we've loved their Throttle shorts for a couple seasons now. They're hard to find these days but Sierra Trading Post has a few left.
The Throttle shorts have an elastic waistband with a flat inside drawstring and a single outside zip pocket on the right hip. The nylon construction and integrated mesh briefs mean they double as swim shorts, meaning the Throttle is the only article of clothing you need to wear on those rare warm-weather, sun and water filled vacation days.
But wait, that's not all! The short four inch inseam and reflective accents let the Throttle do triple-duty as a running shorts, and at a breezy five ounces they won't slow you down. The Throttle is a quiver of one, if you think of your shorts collection as a quiver. Which you shouldn't, that would make you a bit of a tool.
