it depends on season and product.
Jacket : Rafa (almost same size as N98, eugene and chevron jackets)
Federer (Runs smaller than N98, eugene and chevron jackets)
shorts sizes were consistent
shirts Rafa : last year, there was so many confusion regarding on size of rafa's shirts. fed line was consistent.
i found that the Federer spring white/obsidian jacket from last year ran just a little big compared to my chevron jacket, but the eugene jacket was even bigger than that.
