After touring Thailand and Cambodia we will find ourselves in North Vietnam during March. I have read Sapa and area can be chilly to downright cold, with fog and rain that time of year. I do not want to carry cool weather clothes throughout our 3 month trip and would like to buy a sweater and jacket while in Hanoi. Are US XXL sizes available? I am not a fashionista, nor am I adverse to 2nd hand clothing.
Any information is gratefully appreciated.
