The wraparound geometry along with non-slip ear and nose pieces of the Spinshield Air deliver a natural compression fit without undue pressure for excellent comfort and stability. Additionally, Spinshield Air is offered in both standard and Asian fit frames.
For those who normally wear corrective lenses, Spinshield Air is prescription ready via a proprietary Rx optical insert that can easily be clipped to the nosebridge behind the sun lens.
Spinshield Air always delivers a comfortable fit. The ergo-grip integrated rubber tips and nose pads, ensure a snug stable fit while the Pro-Fit geometry of the temples is designed to provide natural comfortable ergonomic fit without annoying pressures on the ear area.
Truly superior performance vs any other sunglasses ive worn regardless of price. I bought a photochromic pair and will put them on pre sunrise and just never take them off through miles and miles of alpenglow, shade, sun, clouds, storms, you name it. The lenses transition transparently to the wearer and the clarity is phenomenal and they are extremely comfortable.
Only a few grams heavier than my other pairs and the weight is so well distributed that i dont even feel them. Longest ive worn them is for a 10+ hour day in the mountains and i basically forget that i am wearing them at all.
They will fog up slightly in very humid and wet conditions. I think its unavoidable though and these will clear up totally with even the slightest of cross breezes or direct sun. I hesitated a great deal in spending more money on these sunglasses than probably the last 6 or 7 pairs of sunglasses ive bought combined but in the end im glad i bought the Cutlines. I hope i never lose them but if i do i would rebuy.
Not to mention, very functional with unobstructed field of vision.
My prescription is not that bad but still, I wish this is Rx ready.
Bought another pair as I did not notice my glasses (which was on back of helmet) fell off midway a long ride.
So I actually ran my glasses over with a 45000 Lb excavator and plowed up the dirt they fell in a few times. They fell off the top of my hat and I didn’t notice. So the lenses had a few scratches, the frames were bent a little , after I straighten everything they actually can still be used!! New set of lenses and a earpiece kit and they would work!! I ordered 2 new pairs!! That’s quality!! And customer service gave me a nice discount code for my new optical insert when I sent them the pics and the story. Im forever customer now.
