These UnderArmor Escape Shorts are great for running any time of the year! Made with wicking material that UnderArmor developed, these have been around for a while and have caused numerous imitators from the likes of Nike and other sports brands. The shorts are comfortable and loose, and even if worn under pants or longer shorts they keep you nice and cool.
I've been using mine for a year and a half and there's no sign of fading or breaking. The quality is superb. It's kept me nice and cool during this time and works well in summer or winter, since sweat is what keeps you feeling both hot and sticky and cold and clammy.
The only problem is that you had better like the colors black, blue, or grey since those are the only colors available. Aside from that and the lack of pockets (and who carries much while jogging anyway?), these are the best shorts for running outside.
