Lighter, warmer, and more comfortable than other men’s ice fishing bibs, the Apex Bib is the most advanced cold-weather fishing system available today. 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 Bib can achieve unprecedented levels of lightweight warmth. Rest assured the Apex Bib is loaded with the same Sureflote® Flotation Assist Technology as all other Striker® ice fishing suits. SuperFabric™ reinforced knees provide a more flexible yet more durable barrier between your bibs and the ice. Fully adjustable elastic shoulder straps with silicone underside help grip your shoulders to work with you throughout the day.
