Necessity is the mother of invention. This was never truer than in the case of our Corduroy Running Shorts. They fill a very specific, almost selfish, need, but offer a perfect solution to a very narrow problem: we want to keep running in shorts no matter how chilly it gets. Pants are too restrictive and clumsy, even in the cold, and tights have never really been an an option. Most running shorts are extremely lightweight and very short--not ideal once the temperature starts to drop. Our English Corduroy, however, offers a perfect combination of durability, comfort, and warmth due to its heavyweight construction and dense weave. The addition of a high-tech, merino wool liner lets these function as a true piece of athletic gear. The length covers just enough to keep you warm, and the cut allows the range of motion needed to move freely. If you're running through the winter, give these serious consideration. To put it plainly, they work, and that's really all that matters once weather becomes a real factor in your daily running routine.
