All a gentleman requires for two weeks in the mountains of Vietnam. We chose to go during Monsoon season but saw only 2 days of rain during our time there but when it rains it rains. NorthFace sells a great drybag that worked well otherwise you can wrap your gear in plastic everyday. You will also need some good water proofs as it usually rains for 30 minutes everyday so its good to keep them handy. i bought a two piece suit in the market in Hanoi for 15$ and it worked perfectly.
