World's lightest 3-layer

These ultra-lightweight 3-layer rain pants are ideal for hiking and fastpacking. They are as light as wind pants and have a simple, easy-to-move silhouette that is slightly slimmer.

Two types of materials are available: the ultra-lightweight Pertex Shield PU hydrophilic non-porous membrane and the Pertex Shield Pro PU hydrophobic porous membrane, which offers excellent balancE

・Ultrasonic welding technology minimizes sewing points
・Tapered, slim silhouette
・Can also be used as wind pants

Seam tapes are applied to the seams of the waterproof shell from the back to prevent water from seeping through the seams. However, seam tape is not very durable, and water penetration through seams is inevitable due to deterioration over timE

Therefore, we have adopted the latest ultrasonic welding technology for sewing rain hoodies, which uses ultrasonic waves to melt and weld fabric to fabriC This minimizes flooding from the joints of the fabrics as much as possible due to age-related deterioration.

Pertex Shield Plus (PU Sosui) is a hydrophobic porous membrane of polyurethane (PU). The term "hydrophobic" refers to its ability to repel water, while the term "porous membrane" refers to the membrane's mesh-like structure with numerous microscopic pores (holes).

These microscopic pores are large enough to allow vapor to pass through, but not water, and Pertex Shield Plus is extremely moisture permeable because the vapor in the garment is dissipated directly from these pores.

Independent tests conducted by Yama to Michi Labo have shown that the temperature inside the garment does not rise easily during activities, and even when the outside air suddenly drops, the temperature inside the garment is maintained. It also outperforms Pertex Shield (PU Shinsui) in terms of durability, according to the manufacturer's published information.

Classification and Characteristics of Waterproof Breathable Materials

Currently, most waterproof shell materials are laminated fabrics consisting of a waterproof and breathable thin membrane sandwiched between a water-repellent and durable outer fabric and a moisture-absorbent lining that is in contact with the skin. The membrane's waterproof breathability technology is broadly classified into two categories: hydrophobic porous and hydrophilic non-porous.
