The Montane Anti-Freeze Jacket features high quality 750+ fill down and a tough weather resistant shell made from Pertex Microlight.

Montane says:


Built for Alpine trips where weight is critical but warmth and fabric water repellency cannot be compromised. 

Features high quality 750+ fill power and updated for winter 2012 to use windproof and water shedding PERTEX Microlight fabric. 

The Anti-Freeze has stitch through construction and small-area midi baffles to avoid down migration and to hug the upper body.  The Anti-Freeze has become a classic MONTANE® style used in the mountains on all types of activities from basecamp insulation to post-race thaw out.    

|Pertex Microlight Lightweight outer Fabric - A good balance between weather & abrasion resistance against the weight of the fabric. Click Logo to read more...

Comes with all the high quality Montane features such as micro fleece chin guard hem cinch cord and neck cord that can close the collar round the neck - toasty! The cuffs have a light elastication and velcro closure combined and the zip is backed by an anti-snag strip fleece lined inner flap.  

The Anti-Freeze is an excellent general purpose layer that delivers a high warmth to weoght ratio and packs down very small - although Montane supplies a waterproof stuffsack it weighs 88g and there are lighter options out there.

  • Down clothing ideally needs to be handwashed. Care must be taken to dry the product correctly. Wash in a mild soap in warm water 40C/110F.
  • MONTANE® recommends Nikwax Down Wash. DO NOT use fabric softeners bleach or liquid detergent. Rinse the product thoroughly after washing to remove any soap traces. You must dry the product carefully in a tumble drier on a cool setting.  You may need to stop the tumble drier at regular intervals to loft the down by hand It will take some time to dry a down product thoroughly even if the outer fabric is dry the down may not be.
