EUC Patagonia Nano puff Long Sleeved Jacket - Mens LARGE Excellent used condition (EUC) Patagonia Nano puff Long Sleeved Jacket - Mens L in Black. It is a synthetic insulation jacket that keeps you warm even when damp. It also folds into its own pocket for packable ease. I purchased this item in EUC here on Poshmark. Never wore it since it black is too stark for me. I prefer color! Priced to move. Originally retails new at $239.00. Please no lowball offers. It's a waste of your time as well as mine. Thank you.
