Product Insights & Style Tips
Mammut Treeline 3-In-1 HS Hooded Jacket for women is built for days when the forecast keeps you guessing. The outer shell uses 2-layer GORE-TEX with a PFC-free ePE membrane for waterproof, windproof protection, while the lightweight inner puffy adds warmth with recycled down. Zip them together for full-on winter, or wear each layer independently as temps swing from bluebird to blustery. Bluesign Approved shell material with a 75D x 75D polyester face and a PFC-free DWR finish sheds drizzle without fuss.
Wearability is all about flexible layering. Pit zips vent heat on uphill moves, a single-pull hood seals out spindrift, and the water-repellent front zip plus hem adjusters fine-tune coverage. Harness-friendly hand pockets sit on the outer shell, while two zip pockets on the inner keep smaller essentials close without bulk. When the weather warms, you can wear just the outer shell or the liner solo, letting your layering evolve with the day.
From Mammut's Responsible Collection, this system leans into recycled materials and practical outdoor heritage. It speaks to the current craving for modular outerwear that moves from trailhead to town, balancing rugged performance with city polish.

Recommended Care
- For outer shell care, machine wash cold on gentle cycle with a mild detergent; close zippers and fasteners before washing
- Avoid fabric softeners and bleach; these can degrade waterproofing and fabric performance
- Reproof with a suitable DWR treatment after washing to restore water repellency
- Dry outer shell thoroughly; tumble dry on low heat or air dry to reactivate waterproofing
- For the removable liner and insulation, wash separately on gentle cycle with cold water and a down or recycled-down detergent; air dry or low heat until completely dry to prevent clumping
- Avoid high heat and direct sunlight when storing; store in a cool, dry place
