The Castelli Alpha ROS Jersey is more than meets the eye and it strives to be your go-to winter jersey this season. It's almost a hybrid between a jacket and a jersey and like most of cuts of Castelli's clothes, it has a slim, next to body fit. What makes this jersey really unique is the double layer front for maximum temperature regulation with each piece having its own zipper. The Windstopper material and seam sealing echoes a similar design ethos of the Alpha ROS jacket, but is suited for temps that are a little warmer.ROS stands for Rain or Shine and Castelli uses that acronym on their premium products offering protection in cooler weather, both wet and dry. The ROS pieces are designed to perform better in the wet and wind than your typical thermal piece and give you more warmth than a rain cape. If it's a deluge of heavy prolonged rain, you might want something a little more impermeable, but if it is damp, misty conditions that we so often see in spring and fall, or on and off showers and wind, this is where the ROS is designed to excel.The Alpha ROS Jersey improves upon last year's jersey with all new fabrics which greatly increase its water repellency and a reduction in seams enhancing its resistance to rain. We also see new waterproof zippers, laser cut drain holes on the rear pockets, and a raw edge waist. The Nano Flex Xtra Dry back offers the most significant non-membrane water protection available and exceptional breathing. It might not keep every drop of rain out but it will leave you as comfortable, warm, and as dry as possible in more situations than any other garment.
