Sitka Jetstream LT: Lightweight Wind Protection Without Compromise - By 1SG Ambassador Tanner Stolz

If you’re searching for a solution to stop cold, sapping wind—from mountain-side drafts to howling tundra conditions—the Sitka Jetstream LT deserves a hard look. Anyone who spends long days in the field knows that wind protection isn’t optional; it’s foundational. From the moment we put the Jetstream LT to use, it became clear that this jacket delivers where previous options fell short—most notably in consistent, full-coverage wind protection, even when not wearing a pack.

Sitka’s Mountain Evo has long been a trusted wind-stopper and a staple for guides, dedicated hunters, and serious outdoorsmen. If that jacket has lived in your system, the Jetstream LT represents a meaningful evolution. For 2025, Sitka has raised the bar with an outer shell that blends lightweight construction, packability, durability, and true 100% windproof performance into a single piece.

In addition to wind protection, we tested the Jetstream LT through multiple days of light, drizzling rain. While it’s not designed as a stand-alone rain jacket, water beaded off the surface consistently, and soak-through was never an issue. It proved to be a reliable layer in variable conditions—exactly what you want when weather windows are tight and terrain is unforgiving. In our experience, the Jetstream LT feels like the final piece that completes the Sitka layering system.

Where the Jetstream LT Fits in Your System

The Jetstream LT is the go-to solution when you need wind protection without added insulation. When your hunts push deeper into the backcountry, there’s no debate about whether this jacket belongs in your pack—it earns its spot every time.

Weighing just 13.6 ounces in a size large, the Jetstream LT delivers softshell-level wind blocking when warmth isn’t the priority and weight savings matter most. With no built-in insulation, it remains extremely versatile. As temperatures dropped, we found it paired exceptionally well with Sitka’s Ambient and heavyweight mid-layer options, allowing us to adapt quickly as conditions changed.

This jacket truly shines during high-output activities where breathability is critical. Whether climbing, glassing, or covering ground, the Jetstream LT breathed exceptionally well and prevented the overheating and sweat buildup that can become a serious liability in the backcountry. It’s a durable, dependable outer layer that protects without restricting movement or comfort.

Technical Features That Matter in the Field

The Jetstream LT is thoughtfully designed to keep your focus where it belongs—on the hunt, not your gear. The low-profile hood stays out of the way while glassing or moving through cover, and the lightweight polyester face fabric is both extremely durable and completely windproof.

Storage is well executed, with three zippered pockets: one chest pocket and two lower hand pockets. Each pocket features a mesh interior lining and is sized to comfortably hold modern smartphones, gloves, or essential gear without bulk or interference.

Final Thoughts

The Sitka Jetstream LT is built for hunters who understand that wind can be just as punishing as cold. It’s for those who value lightweight efficiency, adaptable layering, and gear that performs when conditions are unpredictable. If your system needs reliable wind protection without unnecessary weight or insulation, the Jetstream LT delivers—plain and simple.
