At 8:45pm... the temperature dropped further down to 4 degree C with wind speed of close to 40km/h, it was very very cold. My wife comments that the wind felt like pushing her when blow from back and felt like trying to stop her for moving forward when blow from front.
This kind of temperature and wind speed... if need to be outside for prolong period will need 2 layers of heattech.
Tomorrow i am going to Harajuku, Meijijingumae and Omotesando... will require to expose to the cold harsh weather condition for prolong period, i will wear a mid layer instead of base layer together with my pant.
