Check out the Thermic Kit at your local First Lite Retailer.

The Thermic jacket is purpose-built for bitterly cold days in the treestand or blind and is the coldest weather component of the First Lite whitetail outerwear kit. It's built using 170 gsm PrimaLoft® Gold insulation, sherpa fleece lining, and windproof technology to keep you more comfortable and maximize warmth. Additionally, it's ultra-quiet, durable, water-resistant, and includes our improved windproof technology. The Thermic Jacket is packed with whitetail features, including treestand-specific pocketing, harness pass-thru, removable hood with contoured collar, and new and improved magnetic KitLink™ system. This bomber cold-weather jacket insulates exceptionally well, blocks the wind, allows ease of movement, and wears like iron.
