A new helmet

Been riding in the same helmet for years, maybe 4 or was that 6. Anyway the foam padding in it has started to disintegrate from all the sweat I suppose. Plus it has been kept in the car. Actually have couple, with one in the tack room. So even if they had no falls in them that caused head to ground contact, they probably are due for replacement. But to actually get one that fits comfortably was just about impossible. Even though they still supposedly make the model that I wear, it has been changed and has less padding than the old version. But after trying 10 or so different models it was still the best of a bad lot. As it's not as instantly comfortable as the old model I will put off buying another one and will try more in different stores.
