Big fan of spigen

Spiegen cases are hard to beat on price and quality IMO. My current case is their Mag Armor for my 13 Pro and I like it a lot.

I like the Totallee cases. They are super thin and you can get clear ones so you aren’t covering up the phone’s look.

I’ve been using Bullstrap cases for a bit now and I love them. IDK if I’d describe them as “slim” but they are 100% not bulky.

I’ve used both Pitaka and Mous cases. The Pitaka is much slimmer, but the Mous offers better protection.

Yes they are too expensive, but the Apple leather case is and has been my favorite.

The right size and thinness. And the leather has the right grip, it doesn’t get stuck pulling it out of a pocket, it has the right grip and feel.

For me. Ymmv

Been using the slim LifeProof case with MagSafe and it’s been amazing

I went through way too many cases trying to find one that’s very slim and has a decently grippy texture. Aramid fiber (Kevlar) turned out to be perfect. I’m currently using this Pitaka case and love it. It’s a mere 0.65mm thick. The iPhone 15 ones seem to be thicker and more robust at 0.95mm, but they have the same case shape and grip.

Look at Nomad Goods. I’m using their MagSafe leather case. The buttons are a tad stiff, but other than that, I have no complaints so far. They have non-leather options as well.

It’s holding up much better than the Apple silicon and leather cases I’ve used for this 12 Pro Max till now, and on past phones I’ve used Otterbox and other cases where the silicon tore off within a year.

I’ll be checking Nomad first for any accessories I need from here on. I have a solid metal MagSafe desk stand and a few watch bands from them as well. All are great.

Pitaka Air case, although I probably won't get any case with the iPhone 15 Pro if the titanium frame is less slippery.

Love my Torras Slim MagSafe cases.

Very happy with my Peel case. Super slim and minimalist, still provides a small rim for the screen and has a grippy but unobtrusive texture.
