Castelli Men's Alpha Doppio RoS Jacket, Windproof, Water-Resistant Breathable Insulated Shell for Winter Biking, Race Cycling

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.
VERSATILE USE CASE: Ideal wear through rain or shine, our industry leading Alpha Doppio RoS Jacket performs well through dry conditions as well as providing significant rain and moisture protection, its our most versatile performance jacket for cold weather training we've ever created.
MATERIAL CONSTRUCTION: Gore-Tex Infinium Windstopper 150 outer fabric construction is windproof and waterproof while remaining highly breathable. Double-layer Alpha with Polartex Alpha Direct insulating layer allows you to open an outer wind-protection layer while keeping the insulation layer closed thereby allowing airflow inside the jacket to evacuate moisture while avoiding direct contact with the skin.
COMFORT FIT: Featuring stretch fabrics for an excellent close-to-body fit that accommodates a wide range of body types, a high neck shaped to move comfortably with you, a stretch layered waist with a silicone bead that lies flat without bunching up or riding up. Double layer cuff integrates seamlessly with the use of gloves.
