Some things i practice ..

1. Bring polyster tees. They dry very fast after a wash & can be worn the nxt day.
2. Bring a thin cotton tee - use it for sweaty activities.
3. Bring a 100ml bath shampoo - in case some cheapo hostel does not provide soap. It can be used for washing shirts too & 100ml is enough for 1 wk.
4. To dry washed clothes - roll them like a a swissroll layered with a dry towel. It will dry faster.
5. Buy a hp cam - with 5mp nowdays, the quality is better than some cameras. And u can just flip if out of the pocket for candid moments, so much less hassle + spacesaving. Inconspicous so that ur not identified as a tourist.
