RH+ Zero Womens Jacket is a mild thermal lined jacket for early morning/evening rides where the jacket will need to protect from temperature changes. It has a slim fit with feminine shaping to prevent loose material flapping around as you ride. Insulation Features - Drop tail hem to increase jacket/short overlap when in an aero-position. 5cm elastic hem with silicone improves the contact area with the body and reduces hem movement; allowing a tighter fit, that doesn't squeeze, to stop air getting under the hem.
