Document: this is a really good safety goggle it fits really nice..the shipping didnt take that long tho i really like the goggles
Pros1. They are super inexpensive.2. They provide a pretty decent field of vision.Cons1. They fog unless you remove their lower vents.2. Mine broke the first day using them (The right tab that hold the strap broke). I believe this piece is replaceable.
These goggles are okay, they fog up pretty easy if you don't remove the &#34;vents&#34;(they're actually solid) on either side of the goggles, the foam is also applied in excess and needed some scissors to modify it. The strap is nice and the polycarbonate used for the lens itself is also nice, just needs better housing.
I bought this pair of goggles because I was sick of using my Save Phace Tigre full face mask while playing on a MOUT field in my area. They do fog but to prevent that, take the bottom two "vents" out and you're good to go. They hold up well and are very comfortable. If you're looking to replace your mask or goggles, these are a great choice.
This weekend I had a chance to use these. They are comfortable and wide enough to not impede my vision. I took out the top &#34;vents&#34; even before a played and they did not fog up once. I am tempted to put them back in to see if they do fog. I took a direct shot in the lens and they didn't even scratch. I am very pleased with these goggles.
these goggles are great they never fog they,and are very comfortable and don't have a harsh foam padding like some other goggles.but above all they look sexy as hell! !
these goggles are alright. compared to the other goggles like the flakjak which are about twice the price of these are, these goggles are about the same quality. there are a handfull of cons about these goggles but enough pros to make these worth the money. Lets start off with the cons, these goggles fog up sometimes but that can be fixed with anti fog. The plastic parts of the goggles straps are kind of cheap so i would be careful with them.
Wore them almost 3 hours straight and did not feel any sort of pinching nor did they leave a mark on my head. the only issue i had, and its ever so slight, is that from sweating they started to fog up, but only after about 2 hours of playing, to remedy that there are foam inserts in the top that can be removed with a little finger work. that instantly caused them to clear up.
Very nice goggles. Doesnt fog and it is comfortable. Only bad thing about this is that i cant wear this over my glasses. But overall, great buy AND fast delivery too!
These goggles are great, the foam helps keep the goggles from putting marks or uncomfortable feeling on my forehead. Recommend it for anyone
