It says a great deal that the Montane Mens Deep Cold Down Insulated Jacket is designed to be used on polar expeditions. It will therefore certainly give excellent insulation protection against the most extreme cold anyone is likely to experience.

The secret is of course in the use of down as the insulation material and here there are 400 grams of minimum 90/10 high-quality goose down at 800+ fill power throughout the jacket with the boxwall construction eliminating the risk of potential cold spots. In addition, the PEAQ Down liner is comfortable next to the skin, it is highly breathable to disperse perspiration and it is fast drying as well.

The Montane Deep Cold Down Jacket is tailored so that it will accommodate even bulky layers you may wear underneath as additional insulation.

The careful attention to detail illustrated below – even in relation to the design and features of the pockets – are convincing evidence of the effectiveness of this hugely impressive high mountain, basecamp and polar expedition jacket.

Garment Care

• Pertex fabric contains Durable Water Repellency (DWR) as first barrier in keeping you dry; clean your jacket to maintain this
• Montane recommends professional cleaning service for down products
• If you choose to wash down jacket yourself, it needs to be hand washed and care taken to dry jacket correctly
• Wash using mild detergent in warm water around 30°C (86°F); Montane recommends Nikwax Down Wash
• Do not use fabric softeners, bleach or liquid detergent
• Rinse jacket thoroughly after washing to remove soap traces
• Dry jacket carefully in tumble drier on cool setting; may need to stop drier at intervals to loft down by hand (3 clean tennis balls in tumble drier agitate down to help stop it clumping together as it dries)
• Down takes time to dry thoroughly and takes longer than outer fabric
