The new TRAVERSE down jacket combines heat welded, non-quilt processing and seam tape construction to prevent moisture penetration and achieve a high level of water resistance. The outer fabric is DERMIZAX® MATTE FLEX 2L, which is not only lightweight, but also extremely waterproof and windproof. For extra warmth, the lining features Descente’s own HEAT NAVI technology, actively converting light into heat and boosting heat retention. A new addition this year is a Silent Zipper front zipper that opens and closes smoothly and noiselessly. Parazip Fasteners in the sides of the jacket can be opened quickly with one hand, so while essentially a pullover style, it is very easy to get in and out of.
