Yesterday, I washed all four sets of reins in hot soapy water and hung them up to dry.
Yes, I use these reins and highly recommend them. They come from endurance land. The drape and feel are excellent, I like how they comfortable they are in my hands - not too fat or too thin and nicely flexible, they are extremely well made, and when they get dirty, they're washable. And they come in all sorts of cool colors.
When I ride at the Mark Rashid clinic next Friday, Saturday and Sunday, I'll be riding a mystery horse, and the only horse gear I'll be taking with me are my helmet, my dressage whip - I'm used to the feel of this as well - and a set of these reins. I know the saddles they use at the clinic host's barn, so I don't need to take along a set of these stirrups, that I also high recommend - and that also come in many colors, although this link only has a few colors - I have two sets of them in silver and copper.
More on the clinic later . . .
