I also swear by SSG All Weather Gloves. Riding with gloves for me is a must with my sore hands.
They are pliable, you can move your fingers, make a fist, ultra grippy without being overly grippy. You can wash these hang to dry as many times as you want. I have washed in the washer and in the sink. They are never stiff. They are not hot, and they do provide cold weather warmth to a certain degree. Easy to get off also. Leather was too stiff all the way around, and I couldn’t bend my fingers very well if I needed to. Leather resists movement, the SSG All Weather allows all movement, and also provides some support. They are not tight, but they are just the right tightness. Cheap too.
I have a lime green pair and a navy pair! Fun!
Now for the horse part, I got a 1.5 old and trained her myself (at 3 yrs) and she is very sensitive to all aids. Which means she is light and very responsive to my leg and hands. Also went gaited. A RM. A light in the hand and off the leg horse for me on the trails and arena are important to me. Also have leather reins with reins stops. I ride with 2 hands at all times, that way one hand doesn’t take all the punishment. God gave you two of most everything, so use each equally.
