The Pro Choice Tail Wraps are used for trailering and to prevent rubs while being trailered -- a lot of us use them on show tails the morning off with gel/hair spray to prevent fly aways at the top of the tail.
Neoprene SWEATS which is going to make your horse itch even more and rub even more.
My suggestion is to find out what's CAUSING your horse to rub.
Have you cleaned her teats?
Is she parasite free?
Have you treated her tail for possible fungal problems?
Have you made sure there's no sweat build-up and/or dirt/sand between her back legs?
