The Patagonia Re-Tool X Women's Nano Pullover combines two longtime favorites into one warmer! Re-Tool Polartec® Thermal Pro® fleece and Nano Puff® PrimaLoft® Gold Insulation. The “Brick” quilting pattern holds the Nano Puff in fluffy insulating pockets to keep your core comfortable while Re-Tool fleece is next to skin comfortable, trapping warm air and wicking moisture for a sporty jacket with an excellent warmth to weight ratio. Both Polartec® and Nano Puff stay warm even when damp making this an excellent choice for changeable weather or damp foggy mornings. A nice high neckline for added warmth, elasticized cuffs to keep out the breezes, and zip hand and a chest pocket for stashing the essentials, this is a great all-around layering jacket for the in-between days that layers up nicely for added versatility.
