What Our Gearhead(R) Experts Are Saying: "I wore the Tsirku GTX Pro during a week in Haines and it never let up-not in wind, not in face shots, not in bootpacks. It's bomber without being bulky, and all the features are tuned for riding hard in serious terrain. The Spectra fabric adds real confidence when charging through trees or wrestling gear on a ridge." For deep backcountry missions and big-mountain objectives, we count on the Summit Tsirku GTX Pro Jacket from The North Face. It's built for the steep and the deep-made with GORE-TEX Pro 3L reinforced with Spectra ripstop to handle brutal terrain and weather. Whether we're skinning into a remote zone, navigating alpine ridgelines, or sending big lines inbounds, this shell delivers unwavering protection and precision functionality. A freeride-specific fit with articulated patterning gives us complete freedom to move, while underarm vents and a brushed tricot chin panel keep the climate dialed and comfort high. Its massive pocket layout stashes goggles, skins, snacks, or even climbing skins without crowding, and the integrated powder skirt plus jacket-to-bib clip means we're locked in for storm days. From storm laps to heli drops, the Tsirku is the shell we trust when the lines get serious.
