I bought an RST jean to jacket belt so I could either wear leathers top & bottom or leather top jeans bottom. Later I went to Bikers World in Coleshill to see if they had the jacket zip ( that [mention]raesewell[/mention] mentioned ) that would match my RST leather jacket, I was amazed & impressed that they keep all those extra zips that folks don't want in a massive tub, after trying a few they found one & didn't charge me for it I got the missus to sew it to the Alpinestars air mesh jacket attachment zip to the RST attachment zip so I can also choose leather RST bottoms with Alpinestars mesh jacket. Did all that make sense, I'm tired today
