The PORTER LIFT series features its own glossy nylon fabric and offers items that can be used in various situations, from casual to formal.

The main fabric is an original nylon twill woven using two types of yarn. The warp uses 210-denier nylon yarn, and the weft uses "high-twist nylon hollow yarn," which is made by twisting multiple hollow fibers together. This special yarn is used to weave the fabric at an ultra-high density. By weaving a thick fabric with extremely fine threads, it is lightweight yet has a very voluminous feel and can express an elegant luster like silk. PVC processing is applied to the back of the bag fabric to create a firm tension and body, which not only helps to shape the bag but also prevents water droplets from penetrating inside.
In addition, the embossed name tag, which expresses characters only with unevenness, is pressed from above and below with heat setting on the tape fabric woven at an ultra-high density, just like the fabric, giving a sophisticated impression. Small name tags are used for small items, but the high level of technology to clearly express the characters even in this size is also one of the features.
