I purchased this from the site. I will quote the product description as is.

Ka Lipoa
A surf trunk factory brand based in Koshigoe, Kamakura (Shichirigahama), established in 1997.
All processes are done by hand, and surf pants are carefully handmade one by one.

This is a limited collaboration model with GOAHEAD5GO, based on 60's classics.
GOAHEAD5GO is no longer available, so limited models like this will not be released again.

The front features gray with pink dots, and the back has a vibrant floral print panel.
The waist is a 10-hole lace-up type, with a full poly-cotton lining.
The side finish is triple-stitched, and there is a key loop inside the pocket.
As you use them, the fabric will develop a richer texture, becoming very well-aged trunks.
Since they are made of cotton, they can be worn comfortably and stylishly as everyday shorts.

These are new. The price was approximately 17,000 yen.

29 inches (labeled size M, unisex)
Waist 75.5 cm, Hip 98 cm, Rise 20.0 cm, Inseam 16 cm, Hem width 25.0 cm
*The waist can be adjusted by approximately ±2 cm with the inner tab and lacing.

100% Cotton (Lining) Poly-cotton
100% hand made in JAPAN

I really like the color and design, but they no longer fit, so I would like to pass them on to someone who can use them.
