DC Command Jacket Headlining the DC TRANSITORS packable collection, the Command jacket is a superior lightweight, all-season technical shell featuring a packable design and the advanced waterproof breathability of Sympatex 30K fabrication. At DC, we’re constantly testing the waterproofness of our weather defense technology to make sure it’s exceptionally resistant to heavy weather conditions. These waterproof garments provide excellent resistance to snow, rain, and wind while remaining breathable. There is nothing more unpleasant than wet and cold clothing. Sympatex has therefore developed a special membrane, which absorbs the body water vapor and removes it through the clothing to the outside. This keeps the body warm and dry even in extreme situations. The best thing about it is that the higher the physical activity, the more efficient the Sympatex membrane works. Functional textiles with a sympatex membrane also provide effective protection from low temperatures and rain. Because water molecules are smaller than air molecules, these protective fabrics allow perspiration to escape while trapping essential body heat. Microscopic pores keep layers dry inside so you can thrive outside.
