Arc’teryx Strato Hoodie XXL circa 2013 The Arc'teryx Strato Hoody (also known as the Strato Jacket) is a discontinued mid-weight fleece piece from the early 2010s (circa 2011–2014). It is characterized by its use of Polartec® Thermal Pro® fabric, which provides a high warmth-to-weight ratio and a distinct "cobble" or "grid" texture on the exterior. Key Features and Performance Material: Constructed with Polartec® Thermal Pro® "Cobble" fleece (100% polyester). Design: Features a low-profile hood with a laminated brim, flatlocked seams for comfort, and gusseted underarms for mobility. Storage: Typically includes two hand pockets with laminated zippers and a laminated sleeve pocket. Fit: Reviewers often note that the vintage Strato has a baggier, roomier fit compared to modern, more athletic Arc'teryx designs. It is frequently described as bulky through the mid-section, making it better as a standalone layer than a mid-layer under slim shells. Arc'teryx men's fleece jacket in vivid green. Full-zip design with secure pockets. Soft, plush fleece interior. Simple, versatile layering piece.
