This is really interesting. I'm very active in football(soccer) and perspire a lot due to weather as well. I've noticed how significantly longer a scent lasts on my clothes than on skin. With almost all my frags, the scent develops, dries down and diminishes much much faster on my skin, even after I moisturise using unscented lotion. I've noticed that most scents last at least 3 hours more on my clothes than on skin. I would have no qualms using it on my clothes but then I don't get certain developments of the scent that I get when I use it on skin. for example I was using Montana (red box) recently on both skin and clothes, and noticed how on my skin the spiciness fades really fast leaving a slightly floral settlement(within half an hour), while sniffing my tee shirt, i noticed that even after 2-3 hours the spiciness is still VERY prominent and doesn't settle into the floral linger that i enjoyed on my skin. Its a little frustrating coz on skin i love the development of the scent, but it vanishes way to fast, but on clothing, it lasts long enough, but doesn't give me the nice dry down I desire. Its definitely my skin chemistry, but I too will like to be educated deeper about athletic effects on skin chem.
