This isn't your regular old T-shirt. This is the POC Essential Enduro Light Jersey. That's right, it's an enduro shirt. It has been sewn together from lightweight, moisture-wicking synthetic fabrics by a person or machine (probably machine) whose only thoughts during the entire construction of the shirt revolved around speed. That single-minded (single circuited?) focus on speed, gravity, and extreme rowdiness has created a shirt that is so good at going downhill, it will in fact go downhill all by itself, without any assistance from bike or rider.
