They look like they come straight from the future with their cyberpunk-inspired aesthetic, but I also love how they’re multi-functional

Why It Made The List

An ultra-slim iPhone 17 Pro Max case with real technical bite, built for people who want protection without turning their phone into a hefty rubber brick. The woven 1500D aramid fibre is the draw: tactile, high-tech, rigid in the hand, and far nicer than plastic or silicone. At just 33 g and around 1.2 mm thin, the Pro Max version adds an upgraded aluminium camera frame, full MagSafe compatibility, and an open-side design for easier button access and a more natural grip. The clever bit is the cooling system: a silicone thermal pad and integrated aluminium plate help move heat away, while the colour-shift detail changes as CPU temperature rises. Slim, protective and genuinely different, it’s for design-minded people bored of cheap black slabs.

MORE DETAIL

This design-forward iPhone case is built for people who want a slim, technical case with a more premium feel than standard plastic or silicone.

For the iPhone 17 Pro Max version, the case is made from aramid fibre with an aluminium camera frame, keeping it ultra-thin, light, and structurally strong.

The aramid fibre body gives the case its woven black finish, with a cleaner and more technical look than a standard plastic shell.

Aulumu uses selected 1500D aramid fibre with 3D precision layering technology, giving the case strength without unnecessary bulk.

The Pro Max version weighs 33g and is 1.2mm thin, so it stays close to the feel of the phone while adding everyday scratch resistance, grip, and camera protection.

It’s best understood as a slim daily case rather than heavy-duty drop protection.

The upgraded aluminium camera frame is raised to help reduce direct contact, scratches, and everyday wear around the lenses.

The top and bottom edges are covered, while the open-side frame is designed to keep the grip comfortable and button access unobstructed.

For the Pro Max model, Aulumu includes a cooling system that uses a silicone thermal pad and integrated aluminium plate to transfer CPU heat towards the camera frame.

The heat-sensitive colour-changing detail shifts from red at normal temperature to yellow as the CPU heats up, giving the case a more technical, interactive character.

It’s fully MagSafe-compatible and supports wireless charging, so it works with magnetic chargers, stands, wallets, and other MagSafe accessories.
