got these in today: http://store.nike.com/us/en_us/pd/tech-shorts/pid-849382/pgid-849385
these tech shorts are made of a cotton/nylon combo. very lightweight, much moreso than tech fleece. elastic insets around the waist allow them to sit nicely around your waist. the description says zip fly but my pair is button fly. side tech pocket is just the same as the tech fleece pants. in terms of fit, they are fitted without being tight. highly recommend these for casual and athletic summer wear.
I have a pair of these too in Olive from FNL. Big fan of these. FYI, for me I sized up from my tech fleece sizing and they fit perfectly.
