@jack90 I'd say it would work great for a fun night out in the heat. Not so sure about business casual because of the coloring. Some of the reviews worry me a little as 2 out of 4 of them say the jacket is actually striped rather than solid. Maybe they were through off by the weave of the fabric? If it really is striped I would pass on it.
If you pickup the Deep Water option instead it can definitely pull double duty for work and a night out.
