  • The Montbell Permafrost uses a Gore-Tex Infinium membrane to create a solid windproof down jacket that is versatile and will cover a lot of bases for your needs over winter. 

    Montbell says: 

    Featuring excellent windproofed insulation, this lightweight down jacket provides you with the comfort you need on those pursuits in variable conditions.

    Our Verdict

    The Montbell Permafrost jacket is a full windproof lightweight down jacket that is designed to cover a lot of bases so is useful for a large range of activities.

    The Permafrost uses the Gore-Tex infinium membrane in order to create a windproof outer that helps to keep the warmth in and generate a really good warmth to weight ratio with the 800 fill-power. While not the highest fill weight the Permafrost can act as both a outer later due to the Infinium keeping the wind out, and also a mid layer as a shell fits quite comfortably over the top and there is no restriction of movement. 

    Features wise the Permafrost comes with two good sized pockets on the front, is adjustable via a elasticated cord on the bottom of the jacket and some internal non zipped pockets. 

    As for the fit I found to be good size so there is room for a couple of layers underneath again making it a good outer-layer for dryer conditions, but not too big meaning that it is also a good choice as a mid layer in combination with a base layer. 

    If you are looking for a lighter weight down jacket than has multiple fuctions then the Permafrost is definitely a great choice, given it's wind proof outer and its ability to keep you warm.

    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.
