Women's Alpine Insulated Vest

Lightweight Warmth. Alpine Ready.

Designed for cold-weather training, the Alpine Insulated Vest delivers the warmth of down without the bulk. Featuring gold-standard PrimaLoft® insulation, windproof stretch fabric, and breathable fleece panels, it balances protection, breathability, and mobility for winter runs, layering, and mountain miles.

Technical Features

• Gold-Standard PrimaLoft® Insulation: Lightweight synthetic fill delivers the warmth of 140g down with superior water resistance and quick-dry performance.
• Windproof Stretch Shell: Dual-channel woven fabric blocks cold gusts while flexing naturally with running motion.
• Breathable Thermal Zones: Fleece panels at the back, sides, and collar wick sweat fast, maintaining dry warmth during exertion.
• Thermal Efficiency: Advanced construction retains 40% more warmth when wet compared to wool insulation of similar weight.
• Strategic Pocketing: Two zippered hand pockets plus dual side-entry stash pockets placed high along the ribs for secure, on-the-move access.
• Reflective Safety: Reflective zipper and heat-stamped details enhance visibility from all directions in low-light conditions.
