Heat 3Way Briefcase

The PORTER Heat 3Way Briefcase in Black combines military-inspired design with exceptional durability and water resistance. Made in Japan from varistor nylon woven with 66-nylon thread—the same material used in car airbags and bulletproof vests—it features highly water-resistant tarpaulin accents, PALS webbing, D-rings, and double rings for attaching small items. Thick, high-density nylon at key points ensures a structured silhouette that prevents sagging, while multiple carrying options make it a versatile, professional choice. Sleek, one-tone black with subtle textural contrasts, it balances style, utility, and expert craftsmanship.
