Not much bulk at all, it's probably the slimmest fitting leather bumper case I've used from Samsung and I've had a few over the years with different phones.
Pitaka is the way to go. I get one for all my phones. It's carbon fibre which makes it very light as well as being very strong. It looks so good but then again what looks good is very subjective. Take a look to see if you it's one you could consider. They are a bit pricey though.
Thanks,yeah I have carbon fibre cases on my s22 and s21 ultra. Only thing I don't like about pitaka is they have the buttons uncovered. The one I have on my s22 isn't from pitaka but the buttons are covered.and yes agree with you carbon fibre cases are awesome and probably the thinnest you can get.
