The KÜHL W’S JETSTREAM™ TRENCH is a lightweight, high performance rain jacket made with AIRSKAPE™ fabric. This waterproof/breathable fabric boasts a 20K waterproof rating, 16K water vapor transportation, and a 2.5 layer 15 micron thick hydrophilic PU laminate with blue pearl finish.AIRSKAPE™ fabric has a clear hydrophilic membrane which absorbs and spreads out moisture allowing the fabric to dry faster. The pearl backer darkens as the water disperses before evaporating allowing you to see the technology working. The face is a woven nylon ripstop for mechanical stretch and strength. The surface has a soft hand and is extremely lightweight. All seams have been fully sealed, and the low profile, stretch cuffs seal out cold and wet. The YKK zippers are water resistant. The right pocket converts into a stuff sack with a reflective ribbon loop.
