But the riders’ concerns have yet to reach Back on Track, a market leader that makes equestrian products, including helmets in a variety of shapes and sizes, with removable liners.

“If you have an ‘oddity’ — and I don’t mean to be disrespectful to the people who have weird hairstyles — but if you have a hairstyle that impacts the functionality of the helmet, you might just have to change it,” Mr. Ruder said.
