I've been trying to find the 4 way coat from uniqlo hor, cannot find leh. so sad.
anyway it depends on your tolernace level. I wear like ultra warm down from uniqlo in dec. (about 10 to 6deg with strong wind) + warm heattech + normal shirt + pullover. anyway we always forget about the legs. super freezing cold.
4 way us best lor
but uniqlo stop selling it in 2016
the last 4 way is in 2015
which i find it quite best refresh model
more pocket but too bad i didnt hoot it
hope 2017 they wll make one
since 2016 end of 2017 they only refresh with pure down n a better outer material so the down wont be easy come out poke out lor and more water resistant
as i try before i hoot one of them and use on my 2017 trip walk in the winter heavy rain and it works damm good
but i still wish 4 way better looks more salary man'
if u feel damm cold means the ultra down is not fit for u lor
plus your body cant adapt the cold and cant endure it
get a btter coat lor
and do layer
for me i only 4 way coat and normal long sleeves and jeans
the most is a glove
in sapporo minus 0 or tokyo around sub single digit or 10 deg +
i go saitama is much colder than tokyo so i use my cashmere uniqlo scarf and its ok liao
