Troll omnis. Reasonable price, allow for my very flexible legs and hips without encroaching on my nethers at all. They last forever, are great for outdoors climbing, including esoteric limestone with nettles, brambles and wild roses to complement the ants, wasps and bees. Can be bought in dull greys or black through to bright red, yellow and blue. I am currently hoping they will make me a pair that have all the bright colours in them, but if not I will stick to single bright.
