What Our Gearhead(R) Experts Are Saying: "This jacket is perfect for those in-between days when a jersey and vest just aren't enough. It feels like a race jersey in terms of fit and aerodynamics but has way more warmth thanks to the Rhombus liner. The raw-cut sleeves fit clean under gloves, and ventilation keeps it from overheating during hard efforts." When the crisp air of fall or early spring demands more than a jersey but not yet a full winter shell, the Assos EQUIPE RS Spring Fall 2/3 Jacket S11 steps in. Designed to blur the line between thermal jersey and softshell, it combines sleek aerodynamics with surprising warmth. The front panel uses Push Pull textile paired with the insulating Rhombus liner, trapping body heat while remaining breathable and stretchy for high-output efforts. Full-length raw-cut sleeves made of SONIC-SN fabric offer a compressive, second-skin fit with a brushed lining for added insulation. With reflective details and ventilation features built in, this jacket balances race-ready fit with all-day functionality for shoulder-season training.
