Built with NASA-inspired technology, the Solarcore Beanie delivers next-level warmth without the bulk. Featuring a half-cardigan knit crown, plain knit brim, and fleece lining, it’s crafted for unisex comfort and clean style. The high-gloss JL and Solarcore logos signal innovation beneath the surface. Powered by Solarcore® foam insulation, infused with aerogel — the lowest-density thermal insulator on Earth — this beanie traps heat efficiently without added weight. It’s warmth, re-engineered for performance.
