I've been riding at a western ranch for a woman who doesn't have confidence. FI kept bugging me to get him up on a horse, but with no horse experience, he can't ride the horse I'm riding. The owners of the ranch have agreed to lessons for FI. Should I have him see if my helmet fits? Should he have his own helmet? What about boots? I know the girl side of riding apparel, but no clue about guys. A lot of the ladies at the ranch ride without a helmet, but I do since that's what I was taught since I was little.
