This special model commemorates BEAMS' 40th anniversary, representing the ＜TANKER＞ series from Yoshida & Co.'s ＜PORTER＞, which was first launched in 1983, with indigo dyeing. This is the first time ＜BEAMS＞ has created a special order using navy for the ＜TANKER＞ series. Furthermore, the indigo dyeing of the nylon material, which was considered difficult, was realized through a special formulation by ＜Yoshida & Co.＞. The indigo dyeing is done by hand, so each item has a unique color. It is truly a one-of-a-kind special product.
