Nalini Cotone Base Layer

The first time you put on Nalini’s Cotone base layer, you’ll slap your head and say, “Why didn’t someone think of this sooner?” Forget the clammy, constricting heart-rate belt, this stretchy shirt has a simple fitting in the back that lets you track your heart rate by snapping on any Polar monitor (not pictured). When you’re done working out, unsnap the monitor and toss the layer into the laundry.
