Built for mountain hunts, the Sitka Jetstream Jacket blocks wind and breathes well with GORE-TEX INFINIUM™ and fleece-backed comfort.
Trusted on more hunts than any other jacket we make, the Jetstream Jacket is a rugged windproof workhorse that shields you from the elements without slowing you down. WINDSTOPPER® by GORE-TEX LABS completely blocks heat-sapping winds, while zippered underarm vents keep you from getting bogged down with sweat on uphill assaults. We also outfitted it with a tough softshell fabric with reinforced panels in key areas to help it stand up to the thickest brush and roughest rock.

HOW TO TAKE MEASUREMENTS

The Jetstream Jacket is a versatile layering piece that offers significant wind protection, adequate abrasion resistance, and overall use when afield. As a true soft shell jacket it may not be the most packable layering piece, but when conditions warrant it rounds out one's layering system incredibly well.
