Packable, breathable, low-bulk insulated pants for cool conditions, ideal for layering under rain pants or bibs. The Nano Puff® Pants are so comfortable and warm, even when wet, that you’ll still be wearing them long after you’re off the water. Starting in 2020, we are transitioning our Nano Puff styles to PrimaLoft’s innovative 100% postconsumer recycled polyester insulation made with P.U.R.E.™ (Produced Using Reduced Emissions) technology, which provides excellent warmth for its weight, stays warm when wet, and reduces carbon emissions as compared to conventional production methods.
