I trailer somewhere to ride almost every weekend. Most of the time its somewhere into the mountains of SE Tennessee, where 42 miles can take almost two hours to travel. It's somewhat rough one lane forest roads up very steep grades.
I've never used any kind of leg wrap or blankets.......just a halter and tie.
You really don't need all that stuff, but, it's your money, spend it on whatever makes you happy.
For we wrestle not against flesh and blood, but against principalities, against powers, against the rulers of the darkness of this world, against spiritual wickedness in high places.
