Vesper Insulated Jacket - Men's

What Our Gearhead® Experts Are Saying:

"This jacket is in my pack year-round. It's breathable enough for moving fast on the skintrack and warm enough to wear around camp. I also appreciate the sleek fit—great for layering under a shell without bulk."

We count on the Vesper Insulated Jacket when our days demand breathable warmth that doesn’t weigh us down. Outdoor Research built this piece with bluesign® approved materials and VerticalX™ Eco SR insulation to deliver all-conditions comfort with sustainable performance. Whether we're setting out on a pre-dawn start or navigating variable alpine weather, this lightweight jacket keeps our core warm and our movements unrestricted.

Ultralight ripstop fabric resists wind and water while staying flexible, and stretch-bound cuffs with an adjustable hem seal in the heat. The fit is trim and layer-ready, and when we don’t need it, the whole thing packs into its own pocket. With just the right blend of warmth, weather protection, and packability, the Vesper is a year-round essential.
