The women in customer service at Dover > are great & clued me in to the different head shapes & fit in the different > brands.
This is the key, Janice - head shape. I really like my Tipperary but Karen, who has a rounder head, doesn't like it as well as others. I was lucky being at Equine Affaire in April because I could try on every kind of helmet made (and did) and was able to find the one that fit me best. I have a long head from forhead to the crown and usually have to wear a man size hat - most helmets look like a huge bowling ball on my head. The Tipperary was the best for me. -- Laree
