Mens City Pant
The slim-fit Mens City Pant, Functional and breathable, this high-performance jogger boasts sweat-wicking technology and allows for a wide range of movement—making sure to keep you cool until you hit the finish line. A drawstring at waist lets you adjust the fit.
These are really lightweight which is great for summer. They are really big though. I'd recommend buying one or two sizes smaller.
