[Galaxy Note 3 Accessories] Kangal:
From all my research it seems the best protection for the Note 3 is:

MIME Feather Glass protector

+

Polycarbonate Bumper.

What...Why?!?!

Well, first of all the Note 3 has a more sensitive active digitizer and I think the capacitive sensor's been bumped up a notch.

What that means is you can use screen protectors made of glass to give the screen the extra protection it needs.

These are usually VERY protective, and if given the right conditions should last the length of the phone's lifetime (usually 2 years).

The MIME Feather is the THINNEST glass protector available, sitting at 0.15mm its not that much thicker than plastic screen protectors.

Being the thinnest it should be the weakest of the glass protectors, but like I said since glass protectors are REALLY protective it will be more than enough.

And another point to make, this uses the best materials and machining available. Its just a step up, technologically wise, than the cheap 3mm ones.

So it can actually take a beating as much as those cheap 3.3mm glass protectors (which also tank hits, and brush off scratches as nothing).

For $32... its an expensive investment, but being a one off, its probably worth it.

Bumpers.

Is it weird that the Antenna-gate scandal left us with something genius?

Having a bumper which is scratch resistant, shock proof, temperature proof, and just hands down awesome is just... awesome.

I personally don't like bumpers because I feel like they don't protect the phone's front and back-- the truth is they do.

Having a bumper which sits mostly flush on the sides ...BUT protrudes out from the front and rear angles of the phone is magic.

It means dropping the phone will ALWAYS land on the bumper, and shock absorbed, dint free, scratch prevented.

And bumping your phone will ALMOST always ding the bumper.

What this means is a good, high quality bumper can put less "FAT" on your device and still provide the same protection.

I'm all for efficiency.

And why polycarbonate/VaporMG and not Aluminium or Metal?

It doesn't matter what type of metal you have, surrounding the perimeter of the device creates some sort of "force field" a phenomenon known as Faraday Cage.

An expensive metal bumper made by a reputable company will drop ~1 bar of signal, I'm not sure if NFC and Bluetooth are affected. On top of this, not all metals are the same.

Some are poor shock conductors, and won't really protect your phone.

While TPU can get the job done, its not 100% environment/weather proof. Something like a high quality Polycarbonate (think Nikkon DSLR camera housing) will last longer than your device's lifetime, feel great/grippy, and be as protective. Leather isn't a good choice here simply because its not very sturdy (when its just a thin bumper) and won't be able to absorb as much force as these plastics and amorphous metals. Wood seems like a good candidate... good luck in finding the right tree and the right lumberjack!

In conclusion, a very thin glass protector, and a sturdy plastic bumper.

Together they'll absorb almost all the bumps, nicks, and scratches your phone will experience in its lifetime of normal use.

To get better protection, you can always dial up to a 3mm glass protector and a full-case made of TPU/Glass-Metal/Leather, but I honestly don't think it adds as much protection as it adds bulk !

To get maximum protection for those of you who work in construction on skyscrapers... get a really expensive and thick plastic case. Probably one that has a front cover too. Something not far from Otterbox/Griffin/CaseMate/Lifeproof/Seidio/etc cases. Some of these should survive a car driving over it. Meanwhile lads, enjoy wearing a purse to carry your new blunt-force weapon.

Thank you for reading, and be careful out there : l
