But if clipped to your belt loop, I can't see it bothering even the most sensitive horse, the chemicals would travel behind you. Or could THAT be a problem...you're moving too fast for it to be effective?
Really? Sister and I are going to camp in the Adirondacks
The only thing that keeps you bite free in the Adirondacks is a bug jacket, worth every penny at under $20. They are thin mesh like a fly mask and have a hood that zips closed for head protection. I've worn mine trail riding.
I was hoping it would work for me for riding, but then I read the directions. It says that you are supposed to be mostly in one place for the "bubble" of protection to form. If you move, you are supposed to expect it to take a few moments for it to reform. So, a lesson situation seems like the exact opposite of that. However, for camping and sitting around outside, I'm certainly going to try one. For riding, it's back to the old coating both of us with OFF routine.
