The North Face Aconcagua Jacket - Black - M

It is water-repellent, meaning it can handle light rain or snow, but it is not waterproof and will soak through in heavy precipitation.

Yes, its regular fit and synthetic insulation make it an excellent mid-layer for use under a shell jacket.

The jacket features secure-zip pockets for storing your essentials safely.

It means the water-repellent finish is made without perfluorinated chemicals, which are better for the environment.

Check the inner label of your North Face shell for the Triclimate designation or attachment loops that match the snaps on the Aconcagua.

The jacket is designed with a regular fit; if you plan to wear very thick sweaters underneath, you might consider sizing up, but it typically fits true to size.

The DWR coating has likely worn off; wash the jacket and apply a DWR spray treatment to restore water repellency.

The insulation may be compressed; tumble dry the jacket on low heat with dryer balls to fluff the internal fibers.

Check the track for fabric debris or dirt; gently clean with a soft brush and ensure no internal lining is caught in the teeth.
