It is what it seems to be, a very light, medium quality wind breaker.

CONS There is an inner lining, very thin though, it also kind of sticks to the skin if you get too warm.

PROS Has a nice cinch for the waist,
all pockets are zippered,
nice left side chest pocket.
Hood stays in collar very discreetly.
If you need layers, a single long sleeve T shirt combined with this jacket/and or hat would be very effective.
If you need just a light wind breaker to cut the breeze, its works fine.
Very light and would packet very small.

Exactly what I was looking for.  You can get cheaper ones but they are not Columbia fit and finish.
A GOOD CHOICE FOR ME.
