DeFF Launches DURO Case for Nintendo Switch 2

Tokyo, October 30, 2026

DeFF Corporation (President: Toru Araki; Headquarters: Minato-ku, Tokyo) is releasing the Ultra Slim & Light Case DURO for Switch 2 (model DCS-NSW2DBK), a Switch 2 case made from aramid fiber.

The case is made from Kevlar® 1500D aramid fiber by Arclin (USA). It weighs about 39g and is about 0.9mm thick. A Switch 2 with Joy-Con 2 attached weighs about 534g, so the case adds only about 7% to that. You can leave it on while docking, using the stand, or taking the controllers on and off.

Why We Made It

A Switch 2 with Joy-Con 2 attached weighs about 534g (manufacturer's figure). That's already a lot to hold through a long session, and you don't want a case making it heavier.

Our DURO aramid-fiber cases for smartphones are built on one idea: protect the device without adding more than you need. We wanted to bring that idea to a game console, so this case was designed with weight as the first priority.

Real Kevlar®, Not a Carbon-Look Print

The material is Kevlar® 1500D, an aramid fiber made by Arclin in the US. It's highly impact-resistant and is used in spacecraft, aircraft, boats, cars, sailcloth and bulletproof vests. This isn't a printed carbon pattern. The twill texture you see and the matte finish you feel come from the fiber itself.

Three Pieces, So the Controllers Stay Free

The case comes in three parts: a body panel (about 30g) and left & right grip parts (about 9g for the pair). The grips sit on the controllers, so you can take the Joy-Con 2 off without removing the case.

Inside, five adhesive pads keep the case from lifting or slipping off: one on each grip, and three on the body panel (one along the bottom edge of the panel and one on each side of the lower rail). A spare set of five pads comes in the box.

Laser-Cut Openings

Every cut line is finished by laser and placed so it stays clear of the ports and buttons.

How You'll Use It

• About 39g: roughly 7% of a Switch 2 with Joy-Con 2 attached (about 534g), so it barely changes how the console feels in your hands.
• About 0.9mm thick: a thin shell around the outer edge of the console and controllers.
• Handheld mode: the L/ZL and R/ZR areas are open, so you can pick it up and play.
• Table mode: a cutout on the back lets the built-in stand work with the case on.
• Dock-ready: slide it into the dock with the case on and play on your TV.
• Detachable controllers: take the Joy-Con 2 off and hand one to a friend for two-player games.

You don't have to take the case off every time you change how you play, at home or on the go. It doesn't cover the screen, so we recommend pairing it with our ULTRA HARD GLASS for Switch 2 screen protector (sold separately).
