What with fancy dancy, high efficiency front loading washers today, combined with gentle soaps, and hanging to dry in closet, i bet some of that could be remedied quite well. Some might call some of that "work", and think it's a hassle, but i already do some of that for other fabrics like merino--so i'm used to it. Again, it's a shame there aren't more polypro blends make, also could help a lot. 25% nylon, 10% spandex, etc. included can do wonders.
"Yeah, it smelled some but what doesn't when you're perspiring?"
Gorgeous run way models wearing the newest super duper antiperspirants, or so "they" would have you believe? But, i never really fully trusted or listened to "them" anyways.
