I have been trying to find a modular helmet in a junior size for my petite wife. I have found extra small sizes but they were too large for her. She has tried full face junior sizes and the best fit (not loose) was a junior helmet med/sm. There have been times that her comfort level is such that she would prefer the extra protection of a full face, but the advantages of a modular helmet. Gotta take care of her :s I have been searching the net with little success any help would be appreciated.
