Few things I've noticed since we got some clearer shots in the trailer. The rolled up clear tube Max carried on his shoulder seen here.

You can see the tube rolled down to his back at the beginning of the trailer here

This leads to the square yellow piece hanging on his backpack here

This leads me to believe that the yellow squared piece is a hydration bladder and that could be what the clear tube is for. Similar to one of these

I could be wrong since that's the only shot we have on his back and not very close up. Not sure what else it would be at this point though.
I also noticed he's wearing the same boots on both feet at the beginning of the trailer. The same style boots from Mad Max 2 that
DGSimo posted. You can see them in the same picture above. He's also wearing both of the same boots in this photo.

In this promo photo he has a different boot on one leg

Not sure at what point in the film it happens but it appears he loses a boot and replaces with the one above. Another item I'm hoping we could ID soon, but it also gives costumers options if they want to wear both the same boots or one with the modern style.
One last thing I took notice was the shoulder plate he wears on the jacket is not the exact same one from previous films. Most likely a modern one. Not the best but here's a comparison.

I know the old ones they used were Rawlings football shoulder pads, so these might be from the same brand but on a modern model, just not sure which one.
UPDATE: Looks like the new shoulder plate does have the second strap after all. The angle of the picture taken above seems to be covering it.

I'm wondering now if the plate is indeed the same one from the older films but wrapped in leather and a bit of padding on the side to make it look rounder on the edges. The texture certainly does look like leather in certain pictures.
Anyway, that's all for now. Please feel free to chime in with any thoughts or info you might have.
