After a decade of delivering performance no matter the training session, Tracksmith's workhorse Session Shorts were ready for an upgrade. So, they rebuilt them from the inside out with comfort and durability in mind, starting with a new liner made from an Italian-sourced fabric that's so smooth, you won't even notice it. Designers streamlined the waistband with an integrated drawcord to reduce weight and improve comfort. And they added more storage - 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.Details: Featuring one secure rear zip pocket and three internal drop-in pockets Upgraded with a streamlined elastic waistband and an internal drawstring Finished with an Italian-sourced internal liner that’s soft and durable Made in a high-stretch knit Body Fabric: 92% Polyester / 8% Spandex, 155gsm Liner Fabric: 85% Nylon / 15% Elastane UV Protection with UPF 50+ Machine wash cold with like colors.
