I'll go out on a limb and try to answer your question instead of pointing you in other directions. I'd consider lending my leathers to your hubby -- have done it for a good number of other racers, and others might be willing to lend theirs, too. The SCTA/BNI has a system to assure that the rider at the line is wearing approved leathers -- didn't just borrow a set of "ok" leathers to get through inspection, then go back to his "NO GO" leathers for the run.
But before any of us can make a serious offer of leathers -- some dimensions of the aforementioned husband, please. Height/weight/girth, etc, will make it easier for us.
If you really like this way of spending money (to go fast, I mean) there are a number of leathers manufacturers that make customer fitted suits -- and the cost is very similar to that of an off-the-rack suit. If you're interested I could steer you to at least one of 'em.
Good luck. Come visit Nancy and me at SpeedWeek, and by all means, plan to attend Salt Talks Sunday evening.
