When storm clouds build while scrambling a ridgeline with a loaded pack, the Makalu Jacket is the waterproof jacket to pull on. Its 3-layer GORE-TEX 70D fabric is waterproof and windproof, tough enough for rock and heavy packs, and supple enough to pack well. The helmet-compatible hood, laminated cuffs and dual-tether hem drawcords all adjust to seal out wind and driving rain. What Our Gearhead(R) Experts Are Saying:"On long uphill grinds in steady winter drizzle, I opened the pit zips whenever the climb heated up, and the breathable fabric kept moisture from building up inside. Under a heavy pack, the jacket stayed comfortable from the trailhead to the summit."
