Spyder GRIDWEB 1/2-Zip Fleece

Designed for men who ski, hike, or engage in any outdoor activity in the mountains, the Spyder GRIDWEB FLEECE 1/2 ZIP is a technical midlayer engineered to combine active warmth and breathability in winter and mid-season conditions. It features an exclusive Stretch GridWeb™ fabric with a brushed interior; its grid-like mesh texture forms tiny air pockets that effectively trap body heat. Its composition of recycled polyester and spandex makes it both environmentally conscious and dynamic enough to handle physical exertion. Designed for athletes seeking a versatile piece, it’s perfect for days on the slopes as well as off-season mountain outings.

Active warmth and breathability: GridWeb™ technology in action

At the heart of the GRIDWEB FLEECE 1/2 ZIP is Stretch GridWeb™ technology, a fabric whose knitted grid structure creates air channels between the skin and the outer surface. These channels serve a dual purpose: they trap body heat to maintain a stable temperature during exertion, while simultaneously wicking moisture away from the body. The brushed inner lining enhances comfort against the skin while speeding up drying time—a practical advantage during the fluctuations in intensity typical of mountain outings. The fabric’s lightweight construction prevents excessive heat buildup during active phases, making it an ideal mid-layer for sustained athletic activities.

Fit and Freedom of Movement

The raglan-sleeve design eliminates traditional shoulder seams, thereby removing the most common points of friction during wide arm movements. The standard fit provides ample room to comfortably layer the fleece under a hardshell or softshell jacket, without the fabric wrinkling or restricting movement. The smooth outer surface makes layering particularly easy. The spandex in the fabric provides natural stretch in all directions, ensuring freedom of movement whether you’re skiing, climbing, or hiking.

Practical Features for the Mountains

The GRIDWEB FLEECE 1/2 ZIP incorporates several functional details designed to meet the practical needs of outdoor activities. Here are the key features:

• Reverse front half-zip with YKK® zipper: allows you to quickly adjust ventilation based on the intensity of your activity, without having to take the jacket off.
• High collar: protects the nape of the neck and lower face from cold drafts, especially during descents.
• Zippered chest pocket with YKK® zipper: keeps small items (lift pass, energy gel) secure without adding bulk around the hips under other gear.

Environmental commitment: recycled and PFAS-free materials

The fabric is composed of 92% recycled polyester, supplemented by 8% spandex for stretch. This high proportion of recycled material reduces the use of virgin resources without compromising the fabric’s technical performance. Furthermore, the components are manufactured without PFAS chemicals, meaning there are no perfluorinated compounds in the fabric treatment—a concrete commitment to health and the environment. These two features are part of a more responsible production approach, without altering the fleece’s thermal or mechanical properties.

Whether you wear it as a midlayer under your jacket on cold days or on its own during less intense mid-season outings, the Spyder GRIDWEB FLEECE 1/2 ZIP offers a balanced combination of active warmth, breathability, and freedom of movement. It’s particularly well-suited for athletes looking for a versatile technical piece that can adapt to a variety of conditions and activity levels throughout the winter season and beyond. You’ll find this fleece among the ski apparel available to complete your mountain gear.
