I bought this reflective Hi Viz riding sheet made by Horze via Riding Warehouse during their %25 plus free shipping sale. YEAH SALES!!!! I got it mostly for trail riding, although I don't trail ride anywhere that allows hunting I have heard of poachers in those areas, and I assume that anyone poaching isn't making sure they are shooting a deer instead of my horse.
Since I also ride where there are a lot of mountain bikers I hope this makes me more visible for someone going a high rate of speed.
This quarter sheet is bright yellow, reflective, and mesh which is great for riding in the summer. Although I bought it shortly before it was discontinued there are many other safe options out there.
