I can't say enough good things about this jacket. Kept me completely dry and comfortable biking in western island in rain, blowing mist, wind. Very lightweight makes for easy layering and packing. The hood fits comfortably under my helmet, providing a seamless rain shield and extra warmth without blocking any peripheral vision. Its very smartly fitted and styled to flatter women's curves. Along with the rain pants, this jacket made for joyful riding in what would otherwise would have been yucky (windy, chilly, and wet) riding conditions. Nice long arms, snug collar really comfortable and protective. Small possible design improvement : zipper got stuck several times on fabric next to it... I had to pull it away manually.
I typically wear a women's 6-8 (small to medium) top and the medium fit perfectly.
