The Knock Out jacket from ScentBlocker is designed to be your "go to" piece for hunting in the early season or high temperatures. XLT Lightweight Technology consists of a lightweight, breathable and moisture-wicking construction. Multi-directional stretch fabric provides ultimate comfort and a full range of motion. The safety harness slit allows you to use this jacket with a Spider harness, while the elastic cuffs and waist help keep your jacket and scent where it should be. Last, but certainly not least, is the Trinity Scent Technology. Trinity protection is said to absorb nearly 40% more odor than carbon-based clothing and 200% more than Zeolite based clothing and is lighter and less bulky than conventional scent technology. With the increase mobility and scent absorption, you are better equipped to make the shot on that trophy buck.
