:smilewinkgrin: Lots of good suggestions here, thanks. I think the problem is akin to d365's shirts, you can clean, clean, clean, but the second you heat up, here comes the funk again. I just had one of those really fun, but inevitable mountain bike moments the other day. You know, the one where you land on your head on Texas rock, rip out the palms of your favorite gloves, have scratches and apple sized hematomas on several parts of bod, and your watch gets ripped off of your wrist... then you mutter,"darnit". The good part about it was I also ripped the clip in half that holds the front strap and magnet. I called Osprey and they are kindly sending me another clip. The guy had never heard of the odor problem, particularly since I have worn others for a longer amount of time. He suggested some stuff called Tech Wash, I think... So, I'll take the time before the part gets here to wash it in diswashing liquid, then soak the straps overnight in a baking soda concoction, then full on wash it in the washing machine. Maybe that onslaught will take care of it! If not, well hell, I'll just buy a new one since the wife says, "Buy a new one, it stinks". :thumbsup:
