Great winter cap for the money!
the seam between the ear flap and the cap isn't the greatest or smoothest transition. not on the level of "look" as rapha or assos, but for the money im more than happy. i've worn this from 20-45 deg and it's done me so well. 45 is about the upper limit (for me) temperature wise with the ear flaps over my ears. i can wear this under my helmet, but it's it's biggest adjustability. if your helmet is already there without a cap under it, the risvolto might not work for you.
