The 2021 model is Sugar Cane's best seller jeans and the brand's first slim tapered cut. Since the denim fabric, hardware and construction are the same as the 1947 model; the 2021 version can be regarded as a modern tapered version of the 1947 jeans that is well-reputed for its beautiful fades created after several years of wearing. The high rise is still there, and it has a narrower leg opening than any other Sugar Cane model, still offering a bit of room in the thighs.

Sugar Cane has studied and paid the closest attention to the entire process of recreating vintage denim fabric, such as spinning, weaving, dyeing and stitching. Accordingly, their denim has been loved and appreciated by many denim heads worldwide for a long time, establishing this denim as a timeless classic fabric. The weaving process is slow and time-consuming, with only a limited amount of fabric produced per day on vintage Toyoda shuttle looms. The weft is then driven in with greater force, causing the weft yarns to overlap, resulting in an uneven surface and a tight weave. The denim fabric thus completed is dense and thick, and the more it is worn, the more it develops a bite and a taste. Sugar Cane continues to produce this kind of vintage-based denim today while maintaining old machines in top condition.

The charm of vintage denim lies in the unique unevenness of the colour when it is worn and faded. In order to reproduce this, it is essential how closely the yarn used to make the denim resembles the original. To produce this denim yarn, Sugar Cane uses an American and Zimbabwe cotton blend. The raw cotton selected in this way is twisted into yarn. Still, because the spinning technology was immature when the vintage denim was made, the yarn used was an irregular yarn of variable thickness, which gave rise to the unevenness of the colour fading. In order to reproduce this, the yarn twisting power is controlled according to the unevenness of the yarn at the time, creating an uneven thread that is as close as possible to Levi's 1947 501XX denim.

Although Sugar Cane was born in Japan, its spirit and creation are true to proper American manner from the experience learned at the Army base. By mainly utilizing the denim materials, the ultimate American style symbol, the label has been manufacturing true workwear since 1975. Sugar Cane comprise a blend of traditional dyeing techniques and styling with innovation and creativity in textile development. Their jeans represent the higher end of Japanese selvedge denim.
