For those who consider autumn the "early season" and breaking through ice a normal part of wading: Your pants have arrived. Our new Nano Puff® Pants are made with low-bulk 60-gram PrimaLoft® Silver insulation for a wading experience described by one of our ambassadors as "floating in toasty, puffy warmth." Perhaps even more important, Nano Puffs maintain warmth even when wet - a critical factor in any under-wader insulation. Thanks to the lightweight 100% polyester fabric with DWR (durable water repellent) finish, reinforced seat, zip fly and handy pockets, Nano Puffs work just as well outside of waders as in. Which means, if you’re like us, you’ll keep wearing them in camp or around town long after you’ve hung your waders up to dry.
