Have never noticed that SPECIFIC odour.
[I sleep with them next to my head. Maybe thats why I sleep so good.]
After 2 days out pretty much everythang has an odour, including evrythang that belongs to your mates.
The only odour issue that really causes a prob is the one where an INDIVIDUAL in the party decides to carrry and use DEO.
[tending to be the same individuals who have a never ending supply of clean press t-shirts, jocks etc]
That tends to stuff the ODOUR BALANCE up !
Hiking in
mid winter of course tends to lessen the odour of everything, including possibly the fact that everyone keeps most of their kit on.
After day 4 / 5 as you stroll into the lower camps / hotels, amidst the 'tissue flingers'

and conference goers

you have no trouble moving the crowd.
Then to SHOWER BLISS [unless of course you end at Vergelegen !] and binbag everything.
It certainly wouldn't be the same without ODOURS.
Thats my 6 cents worth.
