Purchased this product for muddy harescramble and GNCC races for the larger field of view they provide. Product had a tab broken on the film cover directly out of the box. The tabs for the tear offs are the worst design I have ever seen. They are rubber posts that aren't fixed to the film canisters. The tear off posts pull completely out of the goggle when tear offs are removed. Any racers knows what it's like to pull a tear off and the whole stack come off. That is exactly what will happen with this poor design. I am completely surprised no one else has written a review about this roll off goggle, maybe no one else was foolish enough to spend that kind of money for what should have been a superior Google. I am glad I bought a regular lense to use with tear offs because it's the only way I will get my moneys worth of this goggle. Last comment: there are no raised bumps on the lense either like other brands so if the film gets wet it is gonna stick to the lense for sure. Don't waste your money there are far better options and I will stick with them.
