Two of Patagonia's popular insulating layers teamed up to create the cozy Re-Tool X Nano Pullover. Soft, warm Re-Tool fleece on the upper body provides techy, wicking warmth, and the insulated Nano Puff-inspired lower offers extra weather resistance with water-repellent fabric and heat-retaining PrimaLoft insulation. The relaxed fit creates a casual look that layers comfortably for autumn hikes and early morning coffee shop stops. Color: natural
