For the battle Caspian wears a Narnian mail hauberk
with a coif under his brigandine.
His weathered, hardened leather pauldrons are three-piece, with
an etched design on each—glumPuddle mentions in his set
report that the design was a lion head. They look rather like
the centaur pauldrons of The Lion, the Witch and the Wardrobe,
which may suggest that they're borrowed from the current Narnian
army, and not custom-made by dwarf-armorers as in the books.
He wears some kind of mandarin collared garment under
the mail, which shows up at the neck, under the vambraces, and
below the brigandine opening. His suede or leather trousers are
different from the ones worn with the main outfit: they do not
button up the sides, and are a darker grayish brown tone.
He wears leather or suede gauntlets in a mustard brown
color. In one image he's not wearing them, leaving them tucked
into his belt.
His hard leather vambraces are similar to his pauldrons.
They attach with two straps-and-buckles under the arm.

from Miraz's castle, so I'm in my Telmarine outfit. And
then I slowly become slightly more 'Narnianized.' As we
move towards the battle, I end up with this kind of great
mix of the two types of outfits. Some of my armor is the
same as the Telmarine army, which kind of highlights the
fact that I'm fighting against what are essentially my
own people, which is quite a hard thing, I think."
