With the MINI Custom Edition, you can choose the fabric and color for different areas of the backpack. Fabric options include our proprietary Pertex®︎07RS-PC and Pertex®21RS-PC developed in collaboration with Pertex, the lightweight yet exceptionally strong Technoforce® Steel, X-Pac VX07, and UX10—the lightest X-Pac currently available.

Available for: Roll-top/Body, Front pocket

A proprietary 70-denier fabric, developed in collaboration between Yamatomichi and Pertex. Designed with an optimal weave and a supple structure that disperses impact, this fabric delivers the lightweight performance essential for backpacks while offering strength that surpasses standard nylon. A special polycarbonate coating adds extra durability by resisting moisture-related wear over time.

Available for: Front pocket

A proprietary 210-denier fabric, developed in collaboration between Yamatomichi and Pertex. With an optimal weave and a supple structure that disperses impact, this fabric balances the lightness needed for backpacks with strength that surpasses standard nylon. A special polycarbonate coating adds extra durability by protecting against moisture-related wear over time.

The 2025 Spring/Summer model will be available in the following five colors, with regular sales starting in May.
Price: MINI (¥32,000) / MINI TS White (¥36,000)

Available for: Front pocket

At 85g/㎡, this is the lightest fabric in the X-Pac lineup. It features a multi-layer construction: a 100-denier ultra-high-molecular-weight polyethylene (UHPE) with a cire finish (high-density treatment) for added firmness, reinforced with a aramid cross-ply, and backed with a polyester film. This combination offers exceptional strength and waterproof performance while remaining lightweight.

When new, the fabric feels notably stiff, but with use, it quickly softens into a supple texture while retaining a crisp structure.

Available for: Front pocket

X-Pac VX07 is a multi-layer fabric comprised of 70 denier nylon on the surface, a water-resistant polyester film in the middle, and a 50 denier polyester taffeta and diamond-patterned black polyester X-Ply material at the back. It is highly durable and water-resistant with hydrostatic water-resistant structural technology.

Available for: Bottom

X-Pac VX21 is adopted for the bottom material of our standard backpacks. It is a multi-layer fabric composed of 210 denier nylon on the surface, a water-resistant polyester film in the middle, and a 50 denier polyester taffeta and diamond-patterned black polyester X-Ply material at the back. It is highly durable and water-resistant with hydrostatic water-resistant structural technology.

Available for: Front pocket, Bottom

This fabric is made entirely from ultra-high-molecular-weight polyethylene (UHPE), known for its outstanding strength and incredibly light weight—so light it floats on water. Despite being lightweight, UHPE fibers are exceptionally strong; in theory, a single 10mm strand can hold up to 20 tons. The fabric is densely woven to achieve top-tier tear resistance, tensile strength, and abrasion resistance for its weight. On the back, a durable polycarbonate coating adds long-lasting protection, resisting the kind of breakdown that can happen over time with moisture exposure. In demanding durability tests, including the “jungle test” that simulates harsh environments, the fabric showed virtually no signs of wear even after 10 years. And because UHPE doesn’t absorb water, the fabric stays light and never becomes heavy, even in wet conditions.

In the diagram below, higher blue values indicate heavier fabric, while higher black values indicate greater strength.

The MINI Custom Edition is a semi-custom backpack that lets you freely choose the fabric and color for the body/roll-top, front pocket, bottom, and zipper from the options below.

The zipper type is chosen to match the fabric’s characteristics. If you select lower-waterproof fabrics like Technoforce® Steel or Pertex® 21RS-PC / 07RS-PC for the front pocket, a lightweight and durable coil zipper is used. For highly waterproof fabrics like X-Pac, a water-resistant zipper is paired to maintain performance. You can choose from 14 color options for the zipper, whichever type applies.

Coil zipper (YKK #5 Coil Zipper)
Technoforce® Steel
Pertex®︎07RS-PC
Pertex®︎21RS-PC

Water-resistant zipper (YKK #5 Aquaguard®)
X-Pac VX07
X-Pac UX10

Please select from two types of back pads below. Both are removable, but function differently.

As a rough guide, we recommend the L size for people over 175cm, but there are people 170cm tall and the L is perfect for them. We recommend trying before buying.

• The length of the shoulder strap is the straight line from the base of the strap to the end of the core material.
• Please refer to the ONE product page for more information on how we measure the length of the back of our backpacks.

While the fabric used is highly water-resistant, the backpack is not waterproof. We recommend using a waterproof pack liner or a rain cover.

Insect repellents containing DEET can degrade the coating of the fabric components, so please do not let them come into contact with this product.
