Great for black raspberries
"Great for harvesting black raspberries or doing any work in the berry patch, like trimming out dead wood. The heavy canvas material stops all thorns, and it's nice that it's just a sleeve instead of a complete shirt or jacket, which would be hot in berry-picking season. The only drawback is that the stiffness of the material makes them slightly cumbersome, but that's what it takes to stop the thorns. It also helps the sleeves stay in place on your arms. Good product, well-made."
