Combining two longtime favorite fabrics and technologies into one warmer the Patagonia Re-Tool X Men's Nano Hoody features a cozy fleece upper and hood done in Re-Tool Polartec®, soft, flexible, and built with both flat seam construction and off the shoulder seam placement for pack stap comfort. Around the body the “Brick” quilting pattern holds the Nano Puff in fluffy insulating pockets to keep your core comfortable. Together these excel at trapping warm air for a sporty jacket with an excellent warmth to weight ratio. Made from two synthetics both Polartec® and Nano Puff will stay warm even when damp, and the ripstop fabric has been treated with a DWR for water repellency making this an excellent choice for fog, mist, and changing weather. Zip it up, flip it up, the hood is classically adjustable with sweatshirt style drawcord and the cuffs and hem have elastic to keep out the chill. With zip hand pockets and a zip chest pocket there’s room to carry the phone, keys, cards… and a beanie hat… so you’re ready to take on the day.
