Sitka M’s Jetstream Vest – Windproof Big Game Hunting Softshell

The Relentless Barrier Between You and the Wind

Wind is the great equalizer in big game country. It cuts through baselayers, steals warmth on exposed ridgelines, and drains energy during long glassing sessions. The Sitka M’s Jetstream Vest is built to stop it—completely.

As the most trusted WINDSTOPPER® softshell vest in the Sitka lineup, the Jetstream Vest has proven itself across more hunts than any other vest they make. It’s a rugged, windproof workhorse engineered for mountain hunters who move hard, climb steep, and refuse to be slowed by cold gusts or abrasive terrain.

100% Windproof WINDSTOPPER® Performance

Powered by WINDSTOPPER® by GORE-TEX LABS technology, this vest delivers a fully windproof barrier while remaining highly breathable. It blocks heat-sapping drafts that rob endurance, yet allows excess moisture to escape during uphill pushes.

The recycled fleece backer provides low-bulk warmth, making it ideal as a standalone outer layer in cool conditions or as a core-protecting midlayer when temperatures drop. It’s warmth without weight—and protection without overheating.

Reinforced Durability for Western Big Game Terrain

From alder-choked draws to basalt ridgelines, big game country is tough on gear. The Jetstream Vest answers with a durable softshell face fabric and reinforced panels in high-wear areas to withstand brush, rock, and heavy pack straps.

Knit fleece panels at the lower torso enhance mobility and layering comfort, reducing bulk and improving fit when worn under a shell. Zippered hand and chest pockets secure calls, rangefinders, tags, and other essentials when you’re on the move.
