safety ratings on vests?
I'm new to the horse forum and I'm trying to figure out what kind of vest to get my 12-year-old daughter. She jumps and does mounted games at a high rate of speed. After a nasty fall last week on hard gravel, I finally wised up and realized I need to get her a protective vest. I've been researching and learning about the safety ratings, but I'm confused about ASTM F1937-04(2010) and EN 13158:2009. Is there a difference? I know in addition, the vest should be BETA Level 3 also. I don't mind investing in a good one...I just want it to be the right one. Been looking at the Rodney Powells, Airowear Outlyne and Charles Owens. Any help would be greatly appreciated! Thank you!
