Blackberry Armour

I've recently had the need to rapidly traverse a very large blackberry patch. Ideally I would do it without actually trampling too many bushes, but even if I were beating a trail, good protection from thorns would be nice.

Denim is definitely not good enough. I've heard that thick leather welder’s gloves are effective protection for your hands when pulling blackberries, but a full body suit of leather that thick would be hot and heavy. Also if you're just trying to push through the bushes, the thorns will snag in the leather, or most any other fabric I can think of, slowing progress and causing more damage to the bushes.

It occurred to me that one could create an effective yet fairly lightweight and breathable scale armour out of plastic. I'm picturing scales cut from old plastic milk cartons (HDPE). It seems to me that while a thorn could be pushed through a thin plastic material like this, unless the wearer smashes a vine between his arm and some other solid object, there won't be enough force, and the thorns would just slide along the surface. Large areas could be made of solid sheets, but it seems like scales would provide much better breathability. The scales would of course have to be anchored so they couldn't flip up, and would need to have no exposed holes where a thorn could snag and poke the wearer. It would need a matching helmet with face shield, and a good way to interface with gloves and boots to prevent the possibility of the sleeves or legs getting pulled back, or small vines getting in.
