Description The Sitka Jetstream LT Jacket is the lightweight, windproof essential that earns a permanent spot on every packing list. Built with 100% windproof WINDSTOPPER® by GORE-TEX LABS, it provides proven protection against harsh gusts while maintaining the breathability and durability hunters need in the field. Designed as a streamlined version of the best-selling Jetstream, the LT offers a low-profile hood with elastic binding for a secure fit over headwear. Quick to deploy and light to carry, it’s ideal for hunts where shaving ounces and staying cool are just as important as blocking the wind.
