DESCENTE / ALLTERRAIN / Mizusawa Down Oversized Mountaineer Down Jacket 2026 Model

DESCENTE (DESCENTE / Mizusawa Down)
A Japanese sportswear brand specializing in the development and sale of performance apparel. Through its "ALLTERRAIN" collection, DESCENTE incorporates years of experience in the sports field into versatile designs suitable for a variety of situations.







An evolved, highly durable premium nylon material
The 2026 model has been updated with a PFAS-free nylon outer fabric.

Beyond environmental considerations, the material has evolved with enhanced durability for long-term use and a more refined urban aesthetic.

The fabric is resistant to whitening caused by wear, allowing it to maintain its beautiful appearance for a long period. In addition, the use of highly color-retentive nylon creates deeper, more sophisticated tones, especially in dark colors such as black.

The supple softness unique to nylon is another highlight, delivering a more comfortable wearing experience than previous models.





"HEAT NAVI" that converts light into heat
The lining features DESCENTE’s original active warmth system, "HEAT NAVI." It absorbs almost all wavelengths of light and converts them into heat, helping to raise the temperature inside the garment.

Not only in sunny conditions but also on cloudy days, it efficiently utilizes even small amounts of light to support comfortable warmth during winter outdoor activities.





Exceptional water resistance that defines Mizusawa Down
One of the weaknesses of conventional down jackets is water entering through stitched areas.

Mizusawa Down eliminates outer stitching through heat-bonded non-quilt construction. In addition, seam tape processing is applied to sewn areas to prevent water penetration and achieve outstanding water resistance.





A certification that is kind to both birds and people
This jacket uses traceable 750FP French white duck down certified by "DOWNPASS."

This certification guarantees that the down has been ethically collected and produced according to animal welfare standards, while maintaining strict quality requirements.

※You can verify the certification by entering the code on the dedicated website. For this model, registration is completed in English, so please select "EN."





The "Para Hood System" allows the hood to be compactly stored, helping prevent water and snow from accumulating around the hood area. Water-resistant zippers are used in key areas to further improve protection.



The high-neck design prevents cold air from entering, while down insulation in the neck area helps maintain warmth. Details such as the inner rib jersey collar, double-layer cuffs, drawcords inside the side pockets, and powder skirt inside the hem enhance wind protection, warmth, and fit.







The "Dual Zip Ventilation" system on the front zipper uses two rows of zippers with mesh fabric between them, allowing fresh air to enter while releasing excess heat and moisture trapped inside the jacket.



"Pit Zip Ventilation" is also placed under the arms to further improve comfort.



In addition to the front pockets, waist pockets are also included.





Pockets are placed on both inner chest areas, providing ample storage capacity without the need for a bag.





While maintaining the sharp and refined image of the Mountaineer, this model has been updated with a more relaxed sizing. It provides enough room to comfortably wear sweatshirts or knitwear underneath, making it ideal for everyday urban wear.
