Curved Leather Eye Patch
This comes in two types - a full eye patch or a partial eye patch.
It's made out of thick leather and then formed into a curve so that it doesn't touch the eye making it comfortable to use.
The full eye patch can be used for many reasons - archery, LARP, cosplay, medical.
The partial eye patch is archery specific - allowing you to see to put your arrow on the string (straight ahead), but blocks your vision of the target from your covered eye when at full draw.
3 colours - Black, Brown and Tan and lots of options for fastening.
Either elastic or different colours of micro-fibre lace. Once you have the lace set to your head size you can slip the patch on or off quite easily without having to adjust.
