This Jacket is the perfect combination of style and function. I have been looking for a jacket of this caliber for sometime. it functions like a cycling jacket but looks very streamline with unique flair. Hand pockets were crucial for me since I commute on bike, they are mesh lined so can be opened for for ventilation. Drop-tail reflector is nice for wheel spray and visibility. The Side reflectors deploy down but I don't use them much since they look kind of weird hanging down but do what they are intended for. Zippered wrist hems are nice for ventilation and a sleek look. Its Fleece Lined so a base layer is all that is needed for most temperatures. Has a back vent to regulate heat but since I wear a messenger bag 95% of the time doesn't do much for me. Wish it had the pit zips like the "Portland" jacket has, as I feel they would be more functional but the Portland doesn't come in a black though thats why I opted for the "Hybrid". The Chest pocket has a headphone port for music. Im 6' 175 lbs and the medium fits just right with a base layer.
