After a decade of delivering comfort and performance no matter the training session, Tracksmith's workhorse Session Shorts were ready for an upgrade. So, they rebuilt them from the inside out, starting with a new liner made from an Italian-sourced fabric that's so smooth, you won't even notice it. They've streamlined the waistband with an integrated drawcord to reduce weight and improve comfort. And we added pockets - three internal drop-in pockets and one external zip pocket designed to limit cargo bounce. The versatility and considered details are what make the Session Tracksmith's best-selling shorts.
