So, Alberto is back with fire in is belly in the Vuelta. Loved his 7 or so attacks on the Arrate, whilst he perhaps struggled to maintain the veracity of each dig, its clear the is a man on a mission, and it made for a very exciting finale indeed. Anyway! can anyone reveal the interesting scallops on the bottom of his jersey? I know the kit is manufactured by Sportful but I was unable to find any info on this pattern... and wondered what it might be in aid of. If you can shed any light, feel free to comment!
