I guess every crash is unique, so it's hard to compare them. But I have, unfortunately, seen several road spills. Despite the accident being far from high speed, the Nivala I saw did the worst. I know, it's hardly scientific. However, the scientific tests are surpassed at the highest level (EN 13595 Level 2) by Hideout Hi-Pro, BKS 100SX and some Scott Leathers' textiles.
I love Rukka's XTR armour, which I find comfortable with excellent coverage. But considering the Nivala's price, I'm disappointed by Rukka's abrasion resistance – it should be class-leading, not the bottom of the class.
