Dressing at ten degrees
Short answer: A long sleeved layer and a light jacket. Ten degrees is the temperature where a single layer of bamboo viscose makes the most difference.
Why ten degrees is difficult
It is too cold for short sleeves and too warm for a winter coat. Most people end up either cold for the first ten minutes or sweating for the last twenty.
What works
A long sleeved layer against the skin and a jacket you can unzip. Bamboo viscose regulates better than cotton because it moves the moisture away when you warm up. See bamboo long sleeved t-shirts for men.
If it is windy
Ten degrees with wind feels like five. Then the jacket needs to be tight rather than thicker. See bamboo clothing for women and bamboo long sleeved t-shirts for women.
Frequently asked questions
Do you need a jacket
Yes, but a light one. It is there for the wind more than for the warmth.
Can you manage with short sleeves
If the sun is out and there is shelter, yes. Otherwise it gets cold in the shade.
What about shorts
At ten degrees most people get cold legs after half an hour.
