The Supercharger Insulated Jacket is incredibly versatile thanks to it's blend of down and synthetic fill, and it's tough and water resistant outer.
Mountain Hardwear says:
Remarkably light, tough and weather resistant while maintaining expedition-level warmth, the Supercharger Insulated Jacket is the new gold standard for alpine insulation.
Mountain Hardwear's Supercharger Insulated Jacket is an incredibly versatile jacket. The bottom part of the jacket is filled with 800 fill Hydrophobic down with a ripstop outer, and the top half is filled with Thermal.Q Elite synthetic insulation with a waterproof Dry.Q Active stretch outer. Yes you got that right, that's 2 different fills and 2 different outer fabrics.
Other than the large amount of warmth this jacket produces, you also get a pretty tough and water resistant outer. We like that they have used Dry.Q Stretch fabric on the shoulders as it's more durable so you will get less wear on the shoulders when worn with a reasonably heavy rucksack.
