Just started cycling long distances and I've noticed that my clothing stinks after a mile or two. I mostly wear cotton clothing. Right now in NYC its chilly and I wear a tee and a hoodie to school.
The odor coming from the clothing during a ride smells "static-y" as my sister calls it, and lasts until I wash them.
I'm pretty sure it's not my sweat because I work out and run on treadmills and I never have had this smell before doing those activities.
Only other times I've had this smell was when I was young and I would run and play outside. Sometimes I could smell it on my sister when she did the same thing.
I'm guessing wind and the sun is a big factor to the smell as I can also smell it on my jeans and sometimes my hair. My friend calls the smell "fresh air" but don't seem too fresh to me..
I haven't bought any cycling clothing yet so don't know if it's the same deal with them too.
