good fit but not waterproof

The rain cap fits well over a KED helmet and makes the road for more visibility. They signal color can be seen clearly. However, the rain back keeps only minor showers really dry. For prolonged rain the rain cap soaked through, so it drips after about 30 minutes through the rain cap. Nevertheless, I use the rain cap often because it keeps the helmet dry so that it can be worn comfortably. Although the leak disappointed with the price, usually one is anyway sweated on longer tours so that the oozing drops do not notice as much.
