The Marmot Women's Megawatt Jacket is an insulated jacket for all-day warmth in cold weather activity. This hybrid brings the heat with the help of 800 fill power goose down with down defender in the hood and torso and Polartec® Alpha® synthetic insulation throughout. Oh yeah, two types of insulation, and both resist moisture. Put it on in the morning, get your hike, snowshoe, climb or whatever on, and go at it all day long. It's lightweight, the pockets are placed high so you can still wear your pack or harness and it packs down small. On its own or as a midlayer, it's a go-to you can count on.

Products on Sale are Discontinued Styles or Colors.

Polartec Alpha

Polartec Alpha
Polartec Alpha is a versatile high-loft fleece that aims to minimize excess heat and moisture vapor in order to provide active insulation. This means you can run around and sweat in cold or otherwise adverse conditions without worrying about being uncomfortable.

Marmot Down Defender

Marmot Down Defender
Marmot Down Defender helps prevent down from clumping when exposed to water or moisture. This allows it to keep its loft, which equates to greater insulation. Nothing will stop the specially treated, highly water-resistant down from trapping warm air next to your body.
