These shorts are made from a stretch woven nylon-spandex fabric that breathes well and offers great durability with the ability to stretch with your body as you move. Like other higher-priced running shorts, the Swiftlands have smooth flatlock seams that won’t rub your skin raw as you run, and they feature a built-in boxer brief liner that hugs your thighs to ward off chafing. The elastic waistband has a drawcord for a snug fit, and its wide design prevents it from digging into your skin when cinched down. It also features a lumbar pocket at the rear, two drop-in waistband pockets for gels, and an additional hidden pocket for stashing a house key. Bottom line: These shorts have everything you need, and nothing you don’t.

A good pair of running shorts should feel like they disappear from your body once you start your workout, and according to reviews, that’s exactly what you can expect. One shopper found them so “super lightweight and breathable” that they “ended up buying a second pair.” Another shopper raved about the shorts’ “super flexible fabric,” and also found it “lightweight and breathable,” adding they “love the liner” because it “doesn’t bind up in the crotch.”
