Great recommendation! This one is intriguing to me, since I think the issue is the velcro strap that attaches my seat-bag to my seat post. I like those smooth plastic sides, too...that shouldn't be abrasive to my shorts like the rough cordura sort of fabric and zippers on my current seat bag are.

I love the looks of my orange saddle bag on my bike, but I can't afford to trash all of my $$ shorts.

I'm also intrigued by this, since I may be in the market for a new saddle and at the top of my prospective list is a Fizik Arione model.
