I've got these, the medium standards are a little but small on my 15.3 but they're ok, nothing really special but they're not expensive. I use them out hacking and light schooling but would spend more if I was competing or jumping, they're good for everyday stuff though and they wash well. They feel really light and they stay in place without slipping.
I have a full set for my TB- he is verry sensitive and gets rubbed easily.
I love them, they don't make his legs sweat (unlike the woof ones) and they do come up well in the wash.
I have the medium for his forelegs and then the large long on his hinds, in the graphite colour.
In fact, i like them so much i've ordered a set for Red- in the coffee colour.
I love them - I have a full set which I use for flatwork and schooling. They wash well and come up good as new. They're very light so I wouldn't want to use them for jumping.
