i have a 686 jacket and some smarty pants. the pants have what look like a belt loop located below the belt level, that line up with the snaps on your jacket. five, believe. you just shove the snap end through and bring it back around the outside and snap it together. seems to work pretty good. just dont forget to unsnap em... im sure i looked like the nUb i am trying to wrestle my jacket around halfway off to get that last snap.
i think they did help, though... esp being a beginner, i spent lots of time diving into teh powder in all sorts of odd directions.
