Excellent wrap around. Not polaroid.

these are just amazing

This is the second pair after a little old lady destroyed the previous pair. Great product for every day use and cycling and walking won't break very easy

Great Value

Use for dinghy sailing, cycling and holidays in the sun. Can't fault them. Why pay a lot more for a badge on the side that no one sees anyway.

Great for the price!

Used them in really bright sun and work well. Nice and light on face. 62cm head circumference and fit comfortably. Slide slightly with sweat after a while but not a major issue!

Best value for money

These glasses are very light and easy to wear. Excellent value for your money.

Great value and quality

Why spend so much on sunglasses when you can have these for so little. Great value and great quality. Have used for many years. Not just used for MTB but also dinghy sailing, windsurfing and general walkabout.

Great style

This is my second pair of these. Yeah, I have 2 pairs now. 1 for riding and 1 for casual. Great quality. Great price. Worth buying

For single use

The lens is made from the cheapest plastic, so easy to scratch even the tip of the own temple scrtached whilst it was in a hardshell pouch. After one use it is full of with marks, grooves, it is a garbage already.

Thank you for your feedback regarding these glasses.
I would like to reassure you that 100% of our sunglasses use tough Polycarbonate which is the ideal material to use when making lenses for sport, particularly cycling to protect the eyes from projectiles.
If you are not happy with the glasses, please return them to us for an exchange as we want to be sure you are happy with your purchase.
