Finest cashmere
Knitwear made exclusively from the world’s finest
cashmere without compromise
Crafted Exclusively with Certified Top-Grade Cashmere Wool
Cashmere wool feels comfortable on the skin and is a delight to wear. It is made from the hair of cashmere goats, which live through Asia’s extreme annual temperature differences, from winter temperatures of -30° Celsius to summer temperatures of over 30° Celsius.
All of UTO's cashmere knits use the finest Grade A cashmere wool, primarily sourced from China and Inner Mongolia. This specific cashmere is exceptionally soft and delicate. To offer further detail, within the Grade A classification, we select the "1st Class" grade. In Japan, this term signifies cashmere of unparalleled fine quality and excellence.
*Cashmere raw wool is graded based on three criteria: fiber length, thickness (diameter/thinness of the fiber), and the rate of foreign matter inclusion.
| Grade | thickness | length of hairs on the fibre |
| A | 14-16 microns | 36mm-40mm |
| B | 19-22 microns | around 34mm |
| C | 22-30 microns | around 28mm |
| Japanese Grade | thickness | length of hairs on the fibre |
| Grade 1 | 14 microns | 36mm-40mm |
| Grade 2 | 14-15 microns | 30mm-34mm |
| Grade 3 | 16 microns | 28mm-32mm |
| Grade 4 | over 16 microns | under 30mm |
| ... | ... | ... |
| Grade 8-9 | 17-18 microns | under 24mm |

Knitwear made from a special yarn favored by cashmere afficionados
Knitwear that customers will wear for the rest of their lives must, of course, be made from materials that last.
UTO uses Toyoboshi’s brand of cashmere yarn called Piara 26.
Its durability allows knitwear to be worn for a long time, and it produces a smooth texture and attractive knit pattern with straight and uniform lines.
Made from a yarn that has been a long-time favorite of serious enthusiasts for its classic look and feel, our cashmere is the perfect material for those who appreciate a straight and well-proportioned weave, perfectly finished appearance, smooth texture, and durability that can withstand the test of time.

Knitwear made of traceable cashmere so you can wear it with confidence
Customers can purchase our knitwear with peace of mind because we verify when, where and by whom the cashmere was produced.
UTO ensures the traceability of our products by going to the wool producing areas in Inner Mongolia and visiting the households that raise the cashmere goats.
For UTO, the process of certifying our cashmere is vitally important for both customers and our brand.

About certification
UTO has all of its sourced cashmere tested by the third-party Ke’Ken Textile Testing & Certification Center in Japan to verify that it is 100% pure cashmere.
The testing methods used for this certification follow the Japanese Industrial Standards established by the Japanese Standards Association.
In addition, UTO conducts certification to ensure that all dyed textile or leather materials contain no regulated aromatic amines, substances known to potentially pose carcinogenic risks.
Every dyeing material and process is tested to confirm that these harmful compounds fall well below the safety limits defined by both international and Japanese regulations.
These certifications ensure that UTO cashmere products are safe, clean, and gentle on the skin, meeting strict standards for quality and product safety.
