The Plasma 1000 Alpine Down Parka represents the lightest mid-weight insulating layer on the market today. Made with some of the world’s thinnest nylon, 1000 fill power goose down, and gram-shaving design techniques, this garment pushes the limits of what it means to be ultra-light. Extremely compact, highly portable, and with more than 40% of the parka's weight being high-lofting goose down, you would be hard pressed to find a warmer jacket at 8.4 oz. Fully functional in 3-season conditions, the Plasma 1000 Alpine Down Parka represents the ultimate “warmth to weight ratio” offering for ultra-light backpackers, alpinists, and anyone looking to cut weight on winter outings.

7-denier Ballistic Airlight Nylon


We utilize some of the smallest fibers and thinnest fabrics available to achieve a highly compressible ultra-light garment. This silky 7-denier shell has the feel of cotton, but is durable enough to withstand the rigors of normal use for an insulated inner piece. Weighing in at a spartan 21 grams per square meter this highly wind resistant fabric is one of the lightest used in the outdoor industry!

Original Sewing Pattern


In simple terms, the benefits of our patented quilting pattern are straightforward construction, reduced seam weight, and improved thermal efficiency. By not forming traditional rectangular boxes or “skipping” stitches we are able to assemble garments quickly with great attention to detail. Additionally, these unique sewing lines minimize areas of fabric to fabric contact that lead to cold spots. Finally, with the use of these open channels our design promotes maximum down loft while limiting the shift of insulation.

Down Sourcing


At Montbell, we source down from both the European and Asian markets to satisfy a variety of characteristics (supply/availability, low cost, consistent quality, humane practices, etc.) and maintain our lofty standards. Every season we seek to balance the superior quality for which we are known and the lowest possible raw materials cost. We change down sourcing companies frequently to insure that our customers have access to superior products at the lowest price possible. In the course of these efforts, Montbell never purchases down from operations that practice “live-plucking” methods. We only utilize down plumes and feathers collected as a by-product of water fowl raised to meet the demands of the food industry.

We will continue to look for sources of down that maximize value to our customers and allow Montbell products to perform at the highest level.
