DESCENTE / ALLTERRAIN / Mizusawa Down Oversized Mountaineer Down Jacket Model 2024

DESCENTE (Mizusawa Down)
A Japanese sportswear brand that develops and sells apparel specialized for sports. The brand has a collection called "ALLTERRAIN," which applies its extensive experience in the sports field to create items suitable for various everyday scenes.







High-Performance, One-of-a-Kind Fabric
The outer fabric is made of "DERMIZAX," developed by Toray. This high-performance membrane provides the highest levels of waterproofing, water resistance, breathability, and low condensation.

With excellent 4-way stretch, supple texture, and marshmallow-like softness, it offers unparalleled comfort.

Additionally, its advanced color reproduction ability is another standout feature, allowing for a deep matte "black" not found in other waterproof breathable fabrics.





+5°C with Sunlight
The lining features Descente's original active heating system, "HEAT NAVI." This system absorbs nearly all wavelengths of light, converting it into heat, providing +5°C more warmth compared to conventional materials.

It efficiently converts sunlight into heat even on cloudy days, ensuring comfort outdoors in all weather conditions.





One of the weaknesses of down jackets has been the seams. In Mizusawa Down, the stitching is replaced with heat-bonded non-quilted processing, eliminating the need for stitches on the outer fabric. Areas where seams are necessary, like the sleeves, are treated with seam tape to prevent water intrusion, greatly improving waterproofing.





Kind to Both Birds and People
The jacket uses traceable, ethically sourced 750 fill power French white duck down, certified by "DOWNPASS." This certification guarantees the down is ethically harvested with respect for animal welfare and meets high-quality standards.

You can verify the certification by entering the code on the dedicated site. This model is registered in English, so please select "EN" when verifying.





The "Para-Hood System" neatly stores the hood, preventing water or snow from collecting. Major areas of the jacket feature waterproof zippers to enhance water resistance.



The high-neck design blocks cold wind, and down is used in the neck area to retain warmth. Features like rib jersey on the inner collar, double-layered cuffs, side pocket drawcords, and an inner powder skirt at the hem improve wind resistance, warmth, and fit.







The "Dual Zip Ventilation" system, used in the front zipper, consists of two rows of zippers and mesh fabric in between, allowing external air to flow into the jacket and vent out excess heat and moisture trapped inside.



The jacket also has "Pit Zip Ventilation" under the arms to further enhance comfort.



Oversized models feature waist pockets.





Improvements in the 2024 Model
The 2024 model includes interior pockets on both sides of the chest, as well as a removable keychain to enhance storage functionality.

The double cuffs have been upgraded to a softer, more comfortable fit.





Maintaining the sharp, sophisticated look of the Mountaineer model, the fit has been updated to a more relaxed size. It’s perfect for city use, offering a comfortable fit even when wearing a sweatshirt or knit underneath.
