Airsofters cannot cope with too much choice. One size fits all, so only need to choose the colour of mask and if you want clear or tinted lens. Simples. What I find amazing is the price difference between colours.
Aye, the most unpopular choice is £70, the most dull (with clear lens) £85, the best imo £105, and the most expensive £125 - and all functionally identical.
