WMX Tactical Paintball Full Face Mask M50 Adjustable Strap with 2 Breathable Fans SAFETY: The goggles are thick and made of high quality, durable resin,test case for your references,tested them with a 350 fps gun on semi and full automatic from about 3-5 metres away,they works well,didn't show any signs of cracking or breaking. The goggles also have a secure lock in system at the edges when you fix the visor into place on the mask so there is no chance of it popping out. COMFORT: The mask's material is fairly flexible but not massively,which can easily protect against bbs. Display size 8.86L*6.89W(inch), fits nicely on face and has rubber on the nose and cheeks inside to add to the comfort. The strap system has 6 points which are easy enough to adjust on head PRATICALITY: The fan canisters work well, two AA batteries are required for each canister(due to shipping safety,package without battery)and the switch is on the outside of the canister below the clip, it is a simple push on/off button. It still does the job however the other side of the mask does fog up slightly when just wearing the left or right. AMAZINGLY: It looks good with pretty much every combination of canisters and helmets,if you purchased it in black and wear it with a black uniform, can't bemorecool,and there are two visors: clear and tinted,matched for your favour. Very good for airsoft related activity against green gas and full face protection.
