[Winter Outerwear] This warmth and mobility are revolutionary! The classic Stretchdown has evolved

From Mountain Hardwear, the mountain sports brand born in California, USA in 1993, comes an evolved version of the “Stretchdown” series, which has been supported for more than 10 years.

At the core of Stretchdown is the brand’s proprietary technology, “DOPPLEWEAVE.” Typical down jackets divide the chambers that hold the down (baffles) with seams, but DOPPLEWEAVE forms the baffles by weaving the outer and inner fabrics together, so there are no seams. Because it makes the most of the fabric’s natural stretch, it moves naturally with you when you raise your arms or twist your body. Down leakage from the seams is reduced, and durability is also improved.

With this evolution, the design now uses baffles arranged in an intermittent pattern. This reduces down shifting within the baffles by up to 60%, and because the down doesn’t collect in the corners, consistent warmth is maintained throughout the jacket. In addition, the boundaries between baffles where heat tends to escape are given small net-like openings, and the jacket adopts a “cohesion insulation interlock structure” that helps down and feathers intertwine to keep the insulating material in place. This reduces cold spots.

The insulation uses 750-fill-power RDS-certified down. It is sourced from certified farms that meet animal welfare standards, and the down is tracked and managed all the way to the final product.

The lineup comes in two types with different baffle widths. The most insulating “Big Baffle” model, the “Stretchdown Parka,” is a hooded style packed with plenty of down in wide baffles, making it a reliable piece even on snowy mountains in the depths of winter or on ski-lift rides.

The standard that defines Stretchdown is the “Medium Baffle.” It strikes a great balance between warmth and mobility, making it suitable for everything from winter hiking and snowboarding to everyday wear in the city. The hooded “Stretchdown Hooded Jacket” is available in men’s and women’s versions. The hoodless “Stretchdown Jacket” can be worn as an outer layer or as an inner down layer under a hard shell, making layering a fun way to build a winter outfit.

All models are equipped with a two-way front zipper for improved mobility and ventilation, a draft flap with chin guard, zippered chest pocket and hand pockets, and an internal drop pocket. The hooded model lets you adjust the fit of the hood with a three-way drawcord.
