1 spray on the back of your neck (just under your hair, once you've put your shirt on - so it doesn't rub off on it!) can be nice in the summer. Maybe up it to 2 in the evenings, or a spray on the back of your neck and a spray from a good distance away on your shirt. Spraying it on your chest and arms like a normal fragrance can get quite stifling on a hot summers day IMO, unless your working in an air-conditioned office.
The summer editions not that great. Smells like the original + windex, and only lasts half as long.
Theres probably a handful of frags more 'appropriate' for daily summer wear, but hey, if you like it - wear it!
