No they are made outside like most firms do. Very few companies make that sort of stuff in house as too expensive to set up. I personally wouldn't wear eyepro unless it is from a more reputable original manufacturer. Only mesh manufacturers I know of are BBA and Heroshark everything else is same few factories in China.
Sorry but can't find anything that points to that. Lots of references on working with partners and helping design but nothing to say actual manufacturer.
Looks like they rebrand and outsource like most Chinese gear firms.
You do realise Amazon is their main distributor right?
