The Montell Plasma jackets are made with the world's lightest premium quality down. Paired with ultralight fabrics and a design that considers weight at every part of the process, you end up with a warmth to weight ratio that is unrivalled. 

Montbell's premium 1000 fill down comes from waterfowl that live in regions with seasonal temperature extremes. The down balls from birds in such regions are characteristically much larger. Large down balls hold more warm air, which translates to needing less down to provide exceptional warmth retention. Montbell down is ethically sourced and a by-product of the food industry. 

*Bonus tip: This is the world's lightest down jacket. If you are looking to save weight, pair this with a Montbell Versalite for a fully capable shell and insulation combination that weighs 246 grams all up.

*Japanese sizing - take one size up.
