PatagoniaNano Puff Pants - Mens

Offering all-day insulation for cold-weather fishing, Patagonia's Nano Puff® Pants are made with low-bulk, 100% polyester (55% postconsumer recycled) 60-g PrimaLoft® Gold Insulation Eco for a wading experience described by one of our field testers as “floating in toasty, puffy warmth.” Perhaps just as important, the Nano Puffs maintain their warmth even when wet—a critical factor in any under-wader insulation.

The ultralight, 1.4-oz 100% recycled polyester shell—with a DWR (durable water repellent) finish and a reinforced, 3.4-oz nylon taslan seat—slides easily in and out of waders. Elastic waistband and belt loops prevent unintentional moon sightings. Zip fly, front slash pockets and zippered rear security pocket provide easy access and storage. In other words, the Nanos work just as well in or out of waders, making them the ideal cold-weather pants that you’ll keep wearing long after you’ve hung your waders to dry.
