Love all the r1 products - Patagonia R1 Full-Zip Jacket - Mens

I really like the two large interior drop in pockets and find multiple uses for them, including storing my Sawyer Squeeze or Mini Squeeze in sub freezing conditions. Full zip allows maximum heat off loading without taking off your garment. Think of topping a summit after a strenuous climb or scramble and needing to evaporate moisture as fast as possible without taking off your pack. As soon as your body temperature is re-regulated, you can start zipping it back up. Combines great with a full zip vest when you need to preserve core heat, but regulate depending on changing physical output rate. Great layering piece when wearing a hat or a hooded outerwear piece.
