I love the MacWets - wear them every day. Very comfortable and give a fantastic grip. The only thing I would say is that they're not wearing as well as I thought they would given the price.
I have MacWets and love them. I can adjust tack etc without having to take them off so they were great through winter. They perhaps dont wear quite so well but i wear holes in all my gloves and have found these have been the best gloves i've had.
I think theres a size chart you can print off the MacWet website and measure your hand against to get the right size. they come in lots of different sizes (not just S M L) so you can get a good fit! hope this helps!
I was a Roeckl person until I tried MacWets last year. Now they do them in brown as well, I only wear these to ride in. I am so used to being able to adjust bridles etc whilst wearing them and when I had to ride in my old gloves the other day, I couldn't believe how clumsy my hands were trying to put bridles on etc.
