The HEAT series combines two different materials with excellent durability and water resistance, and has a rugged and stylish design.

Since the series was announced in A/W 2001, Porter has added items that match the lifestyle of the time, and have a rich lineup that can be used by a wide range of people, from business bags to accessories.

The main material is Japanese-made varistor nylon woven with 66 nylon thread, which has excellent heat resistance, friction resistance, and tear strength, and is also used in car airbags and bulletproof vests. Some parts are made of highly water-resistant tarpaulin fabric, which is used as an industrial material. Although it is one-tone black, it has a stylish design with contrast by combining fabrics with different textures.

Another key point is that it uses military gimmicks throughout and uses PALS (Pouch Attachment Ladder System), which allows you to attach pouches and accessories by sewing nylon tape at regular intervals. D-rings and double rings are also attached to the main body so that you can coordinate your small items such as carabiners and wallet chains.

Thick nylon tape woven with high density is placed on the main body of the bag at key points to prevent the fabric from sagging, giving it a three-dimensional silhouette and good handling.
