D-Shell Outer Fabric

D-FY.IT 1 is constructed with D-Shell  — a custom-engineered outer fabric built from 840D ballistic nylon base, externally coated with a matte 5PM polycarbonate layer. This combination offers outstanding resistance to abrasion, weather, and surface damage, without compromising on weight or flexibility.

01

Abrasion Resistance

The polycarbonate-based 5PM coating significantly increases abrasion resistance. In ASTM D3884-09 testing, 5PM-coated ballistic nylon achieved up to 5170 abrasion cycles, compared to 2160 cycles for standard PU coatings—a 139% improvement.

02

Tear & Tensile Strength

The 840D ballistic nylon base provides excellent tear and tensile strength, particularly effective in load-bearing zones and high-friction environments.

03

Scratch & Weather Resistance

The polycarbonate topcoat offers improved resistance to surface damage from sharp tools, creasing, and environmental wear—outperforming traditional PU coatings.

04

Matte Surface Finish

D-Shell features a matte, low-sheen finish. This reduces reflective glare, enhances color depth—especially in black—and maintains a consistent premium look over time.

Interior Lining: Soft, Durable, and Waterproof

The interior of D-FY.IT 1 is lined with a custom-developed 70D nylon fabric, designed to balance premium feel with practical performance. The fabric features a silky-smooth inner surface for effortless access and an external 10,000mm waterproof coating to keep contents dry.


Soft Touch, Smooth Handling
The 70D nylon interior is smooth to the touch, reducing friction and allowing gear to slide in and out easily. It contributes to a refined, high-quality feel every time the bag is opened.


Waterproof Backing (10,000mm Rated)
The outer side of the lining features a 10,000mm waterproof coating—capable of withstanding heavy rain or internal spills without leaking. This is equivalent to protection levels used in technical outerwear.


Lightweight, Yet Durable
The liner material is lightweight enough to avoid bulk but durable enough to handle regular use without tearing or breaking down.
