50D BLACK UHPE Fine Grid

The 50D BLACK UHPE Fine Grid is our proprietary fabric that uses 70 denier high-tenacity nylon with extremely tough and light 50 denier ultra-high molecular weight polyethylene (UHPE or UHMWPE) fiber* woven at 2mm intervals as a ripstop.

The regular BLACK UHPE is uses a more heavy-duty 200 denier high-tenacity nylon and 200 denier ultra-high molecular weight polyethylene (UHPE or UHMWPE) fiber*. The result is a fabric weight of 68g/m2 (regular BLACK UHPE is 128g/m2), making this fabric significantly lighter.

To keep it light, only the front surface has been treated with a durable water-repellent treatment, whereas the backside is not coated. Use a pack liner or waterproof stuff sack to keep your items inside dry. Being non-coated means that the fabric is highly resistant to deterioration from hydrolysis and general use.

*UHPE fiber is also known by trade names such as Dyneema or Spectra. It is an ultra-high molecular weight polyethylene material that is extremely strong and lightweight.

Limited Production with
Prototype Fabric

Akira Natsume, Yamatomichi Founder

The Black UHPE Fine Grid, which took five years to develop with a Taiwanese manufacturer, has now become a mythical Yamatomichi fabric with the difficulty of continuing on production due to pandemic related reasons.

The 50D BLACK UHPE Fine Grid was prototyped in the process of developing BLACK UHPE Fine Grid. However, the 50D version wasn’t adopted due to high cost and the difficulty of production.

Still, we believe that it is an amazing fabric, being lighter than the fabric currently being used for MINI2, the contrast between the white and black UHPE ripstop is very cool.

The MINI2 50D BLACK UHPE Fine Grid is a limited production backpack using prototype fabric. Considering the price of the fabric, the sale price should be higher, but we have decided to sell it at the same price as the existing MINI2, taking into account the fact that prototype fabric is used.
