The Graviton Jacket from RAB is a men’s stretch fleece vest designed for active outdoor use. With its full-length zip and slim fit, it works well as a midlayer on cool mornings or as a standalone piece during milder weather.
Made from 96% polyester and 4% elastane, the Graviton Jacket combines warmth with a bit of give for unrestricted movement when you’re hiking, climbing, or just hanging around camp. The close-to-body cut layers neatly under a shell, while the recycled polyester content (89%) cuts down on waste without compromising on durability.
At the heart of this fleece is RAB’s Thermic-G technology, a high-loft construction that traps air to retain heat. High-loft fleece means the fabric fibers are built with extra thickness, creating insulating pockets of air that keep you warm. Despite its warmth, the material remains breathable, helping to manage moisture when you’re on the move.
