FABRIC: Gore-Tex Infinium Windstopper 150 fabric provides wind protection with high breathability and effective rain protection. Water-resistant YKK Vision zipper slides easily to regulate airflow. Stretch fabrics with advanced patterning make for an excellent close-to-body fit that still accommodates a wide range of body types.
STORAGE: The Alpha RoS 2 features 3 rear pockets with reflective laser-cut drain holes, and a zippered secure side pocket for valuables.
WATER REPELLENT: Reduced seaming with seam sealing on shoulders reduces chances for water to enter through stitching. Double-layer Alpha construction separates insulating layer from wind/water barrier to let you better regulate ventilation.
SIZING: Castelli products have a close-to-the-body fit to maximize aerodynamics and performance. For a less compressive feel, or if your measurements fall between sizes, we recommend that you size up.
