The HEAT series from Porter-Yoshida & Co. combines highly durable modern materials with military functionality to create a range of bags that are rugged, practical, and stylish. The main material used in their construction is a Japanese varistor nylon, woven from heavyweight 6.6 nylon thread — similar to that used for car airbags and bulletproof vests. The high-strength canvas, which provides excellent heat, abrasion, and tear resistance, is then paired with an industrial-grade tarpaulin for durability and water resistance in areas of the bag where it’s needed most.

This tote-style bag offers a large-capacity main compartment, making it a versatile choice for shopping trips, the gym, or day outings where you just need to throw everything in one bag and hit the road. Key features include four smaller internal pouches, a zippered outer pocket to organise valuables and essentials, and a two-section Pouch Attachment Ladder System (PALS) for attaching small items such as keychains and carabiners.

To enhance the package, each HEAT series bag is also supplied with a Porter engraved mini Maglite torch, complete with battery and storage case.
