The latest addition to our Triclimate® line delivers on the same core promise: two layers of protection for three different climates in one package. The Kabru Zip-In Triclimate® Jacket is ready for any mountain weather. The outer shell is made from waterproof and breathable DryVent™ fabric technology. The inner jacket features warming Heatseeker™ insulation. Wear then together when it’s cold and wet. Wear the shell alone when it’s wet and mild and wear the inner jacket by itself when it’s cool but dry.
