Black Yak SIBU Hybrid Jacket Men's

What's in a name' Everything, especially when it comes to the Black Yak Men's SIBU Hybrid Jacket. Designed specifically for a wide range of aerobic pursuits, the SIBU Hybrid Jacket features body mapped insulation to provide strategic and adaptive warmth in areas that you need it most. A layer of water resistant, traceable down in the core area of the jacket regulates your temperature. Meanwhile, the PrimaLoft Gold is placed near the waist and arms to provide water resistant warmth. A hybrid jacket would be rendered useless if it wasn't equipped with some semblance of pliable fabric, which is why the designers at Black Yak fashioned with SIBU hybrid with Polartec Alpha for passive ventilation, unimpeded mobility, and full range of motion.
