Just Right!
The material is sports wear - light, breezy and silky to the touch.
Pattern/Design came out as expected from the image, no errors and I tend to choose 1 size up so Medium - Large are my go to's.
Fit well with spare room to fill.
Worth the money.

I got this for my husband for Christmas and he loves it!!! He recently got a corporate job and was in need of something nice and durable, that would also last a long time.
It has just enough space for all his things. He also has received so many compliments on it!
We def recommend!
