The AntiFreeze 2.0 Jacket is Montane's updated version of the Anti-Freeze Jacket, with a few key improvements. The outer is constructed from 100% recycled Pertex Classic Eco that is completely windproof and showerproof with a comfortable PEAQ Down lining which is highly breathable and fast drying. It's filled with 200 grams of 650+ HyperDRY down which is high quality, water resistant down. The down fill power is a little lower than the previous version however there is an extra 30 grams of down in this new jacket, making it a little warmer but also a little heavier.

The jacket no longer features an outer chest pocket however the large inner zip chest pocket makes up for that. It also has 2 large hand warmer pockets for keeping your hands warm and protected from the weather. It also features a full length reversed zip with micro fleece on the chin guard and around the neck for extra comfort. The lower hem and cuffs are adjustable which helps to prevent spindrift entry and heat loss.
