Sorry to hear about your jacket and pants dilemma. I love the Alpinestars brand for motorcycle gear, as their jackets and pants are comfortable and protective. As for sizing, it's always best to check the brand's size chart and measure yourself to ensure a proper fit. I haven't tried RCI gear before, so I can't compare, but a double-layer bag can be a bit warmer and heavier but provides more protection. I've also had good experiences buying UK men's tuxedos at
