The Montbell Plasma 1000 Alpine Down Parka provides the ultimate warmth at an ultralight weight.

Montbell says:

The Plasma 1000 Alpine Down Parka represents the lightest mid-weight insulated layer available today. Made with some of the world’s thinnest nylon, 1000 fill power goose down, and gram shaving construction techniques this garment challenges the limited definition of Ultra Light kit. Extremely compact, highly portable, and with more than 40% of the parka weight being high lofting goose down it may not be possible to find a warmer 8.4 ounces when planning your next backcountry adventure. Fully functional in 3 seasons we see the Plasma 1000 Alpine offering as the ultimate “warmth to weight ratio” performer for the ultra light backpacking crowd, but just as useful during done in a day winter treks, ski mountaineering missions, or the occasional group snowshoe outing.

Montbell's Plasma 1000 Alpine Down Parka is a top tier piece of kit. The jacket is aimed at the ultralight crowd in every aspect of its design.

The stitching pattern across the jacket, with its interconnected baffles, allows the 1000 fill power down to loft uninhibited providing the best warmth to weight ratio of any jacket I've ever tested. The fact that over 40% of the jackets weight is down is a testament to how well designed this jacket is.

Montbell have continued with their extra baffle along the back of the neck design which stops any cold draughts occurring down the back of the jacket like with many competitors. This combined with the adjustable hood and waist hem, really prevent any cold air getting inside this jacket.

The only downside to this jacket is that there are no inside pockets which are found on some of Montbell's other jackets.
