These are herringbone trousers from KANEMASA PHIL.

"Ideal": the ideal silhouette.
The silhouette is just the right amount of loose, but has been carefully designed to prevent the material from sagging too much.
It features a slightly small, narrow short collar.
It is knitted in a high-density typewriter weave using a custom-made 36-gauge circular knitting machine.
We use the finest yarn that can be knitted on this machine, 1/60 super 120 non-mulesing wool.
In addition, the final process of fabric shrinking makes it lightly fluffy, resulting in a high-gauge Melton fabric.
This textile combines luxury with a rough feel.
Of course, it maintains the functionality of wool (heat retention, antibacterial properties), while being a unique wool material that has the smooth feel of knitwear and stretch.
The herringbone pattern is evenly spaced and has the thickest pitch possible, and of course it can be washed at home.
This is a material that can be developed and its texture improves with repeated washing.
Slacks with deep pleats.
It features a moderate width and a slightly tapered silhouette.
The front is designed in Tengu style, giving it a dressy feel.
These pants can be worn for any occasion.
*Filling: A wool finishing process that makes the fabric denser and entangles the ends of the fibers to create a felt-like texture.
*Non-mulesing wool: Mulesing is a method of raising lambs by cutting off the skin and part of their body from their buttocks to prevent maggots from infesting the sheep that produce wool.
In contrast, non-mulesing wool is obtained without the painful mulesing that is done to the sheep, and is obtained through gentle rearing methods that allow the sheep to live in their natural environment.
