The Patagonia R1 fleece is a technical garment designed for men who seek versatility and comfort in outdoor activities. Its hybrid design and advanced materials offer a perfect balance of warmth, breathability and freedom of movement.This fleece stands out for its Polartec® Power Grid® fabric, which combines a main body made from recycled polyester with spandex to provide stretch and durability. The underarm and side panels are made from a lighter, more breathable fabric, improving ventilation and preventing overheating during exertion. Its slim fit and half-length front zip with chin guard ensure a comfortable, secure fit, ideal for wearing under a jacket or on its own on cool days. In addition, it features a zipped chest pocket with a design intended not to interfere with Backpack straps.
