For this specific jacket, one should order a size larger than what usually fits them. I had tried it on before in a store.

Just got it and wearing it
Looks very good and quite warm with a thin sweatshirt
It has three external and two internal pockets
The hood is NOT detachable
It has the hole for the thumbs
(I will update for additional information)

In the cold of Thessaloniki, it is useless
And in Kythira, of course, the same
On its own, it does almost nothing
Of course, it may be because I don't put my hands in the pockets, so I get cold all over
But still, it's not that warm
In terms of quality, it is like it was on the first day
