Hey guys, i will be going to hanoi in mid/ end jan and also sapa highland. Checked the weather in sapa may drop till 5 celcius. With rains perhaps.

Thought of buying uniqlo heat tech as inner layer, then will either bring a uniqlo fleece jacket as mid if needed. Then outer at first thought of buying uniqlo down jacket ( the one which is lightweight and can be packed nicely) but looked rather fragile to me to go trekking and wont stand the rains too.

Any recommendation what to get as outer layer which is both water resistant, windproof and can withstand cold. Plus point is it is easy to keep too as im a backpacker and prefer lightweight

Best to wear 2 layers only or else ended up too bulky. Which is inner with heat tech plus outer.

Understand inner must be really body fit right?

Thank you dear gurus
