Lighter, warmer, and more comfortable, the Apex Jacket is the most advanced cold-weather fishing system available today. Traditionally, using a higher insulation value increases warmth. But doing that also adds weight and unnecessary bulk. PrimaLoft® Cross Core™ Insulation Series fuses existing PrimaLoft insulation fibers with Aerogel, a NASA-developed technology known for being one of the best insulators on the planet. Comprised of more than 95% air, Aerogel is a highly porous, lightweight structure that has an incredible thermal barrier. By utilizing this technology, the Apex Jacket can achieve unprecedented levels of lightweight warmth at only 80g. Rest assured the Apex Jacket is loaded with the same Sureflote® Flotation Assist Technology as all our other suits. If traveling to and from your fishing spot means firing up the sled or ATV the 3-point adjustable hood and reflective elements throughout are critical design elements that keep you safe and protected.
