I have but found that the glove part didn't lend itself to being able to get hold of finer material, gauntlets were great at covering arms but out weighed by gloves that were too thick - I put a jacket on to cover arms and take it off when i've finished if weather is warm.
I've just ordered some gauntlets from Amazon, I'll let you know how good they are, I'm still waging war on brambles, chopping them down then digging out as I clear the space above. so I don't get ripped to shreds. I did try wearing a fleece, but got fed up with the thorns getting tangled on it. When the gauntlets arrive I'll let you know if they are any good (or not, as the case may be).
I used to ride a motorbike (which is long gone) but my leather jacket still comes in very handy when cutting the hawthorne and wild rose hedge!
