This guy's only 18ga and appropriate for costume and dresswear and display (and maybe foam or feder contact in a light touch system); but he's something most decorative/costume great helms don't have these days: he's swol. Yeah, a good bit bigger than the barely-fits-on-your-head run-of-the-mill 18 gauge great helms - a full 31" around at the eyeslot level. Fully wearable by big people, and it comes with a suspension liner and chinstrap (see the interior picture).
height: 13 3/4" front
height: 11 1/2" side
circumference: 31"
weight: 3 lb 13 oz

-- but see the late 13th century great helm for a (standard sized) 16 gauge version of this helmet.
