What is the Anti-Freeze Jacket?
The Anti-Freeze Jacket is an incredibly versatile cold-weather down jacket, perfect as a mid-layer or a standalone belay jacket. The 750+ fill down keeps the weight and pack size very respectable for a jacket of this calibre.
What is the Anti-Freeze Jacket made from?
Insulation: The largest contributing factor to the Anti-Freeze’s pack size and weight is the quality of the insulation. Montane use 750+ fill power water resistant HyperDry goose down to provide high amounts of warmth without the weight penalty associated with lower fill powers. The down is coated in a fluorocarbon-free hydrophobic treatment to improve the down's performance in damp conditions; this means it will dry faster, won't absorb as much water and will loft better if it does happen to get a little soggy. This does not make the jacket waterproof, and we would still not recommend using this in heavy rain without the use of a shell. All of the down used by Montane is also RDS (Responsible Down Standard) certified, meaning the birds have lived a happy and free-range existence before the down was collected.
Outer Fabric: Montane use the ever-reliable and high performing Pertex Quantum 20D fabric to hold all this lovely down in place. Pertex Quantum is light, weather resistant and extremely packable, making it ideal for high mountain adventures where you'll be layering and de-layering more frequently and will need to pack the jacket away. This fabric is coated in a DWR (durable water repellent) to allow rain to bead and roll off the surface. The combination of the high quality down and the lightweight Pertex outer fabric means the jacket weighs just 512g (size Medium).
Inner Fabric: The inner lining is made from FEATHERLITE Mini Rip-stop, a nylon liner with a great next to skin feel and smooth touch to make layer addition/removal a breeze.
What are its features?
The Anti-Freeze features a helmet compatible roll-away hood with 3-point adjustment and a stiffened peak, a full length two way ykk zip with internal storm flap and articulated arms for high reach movement. These features make the Anti-Freeze a great climbing/belaying piece in cold conditions.
Other features of the jacket include a single zipped chest pocket and two zipped hand pockets, along with an internal mesh drop pocket, pre-elasticated cuffs for easy glove compatibility and an adjustable hem with cinchable drawcord. All of this can be stuffed nicely into the included waterproof storage bag from Montane.
How does the Anti-Freeze Jacket fit?
The Anti-Freeze features a relatively long, slim fit, designed to be low bulk and fit close to the body, or to be layered with other non-bulky garments. It is intended to be used for faster-paced mountain activities. There is enough space to fit layers underneath the jacket if needs be, or a shell over the top if the weather takes a turn for the worst.
Where does this fit in the layering system?
The Anti-Freeze is primarily going to be used as an outer layer, however thanks to the slim fit and lightweight outer fabric, you're able to slip a shell over the top without an issue. It can also be used as an over-layer when stopping to belay, have lunch, coffee etc.
