Treeline 3-in-1 HS Hooded Jacket adapts to any forecast with GORE-TEX protection and warm zip-in insulation
What Our Gearhead® Experts Are Saying:
"I’ve been rotating the Treeline 3-in-1 HS Hooded Jacket through shoulder seasons and winter hikes. The ePE GORE-TEX shell is legit waterproof and breathes well on climbs, and the recycled-down inner is cozy on its own in town. Being able to wear either piece solo or zipped together makes packing simple for unpredictable weather."
We reach for the Treeline 3-in-1 HS Hooded Jacket when the forecast can’t make up its mind. The outer shell uses 2-layer GORE-TEX with a PFC-free ePE membrane for waterproof, windproof protection, while the lightweight inner puffy adds reliable warmth with recycled down. Zip them together for full-on winter, or wear each layer independently as temps swing from bluebird to blustery.
Dialed features keep us comfortable on the move: pit zips dump heat on uphill grinds, the single-pull hood seals out spindrift, and a water-repellent front zip and hem adjusters fine-tune coverage. With harness-friendly hand pockets on the shell and two zip pockets on the inner, this modular system keeps essentials close and our layering streamlined from trailhead to town.
