## Description

Product description

Review: Glasses are good to go - Meets and exceeds expectations. I find the tint perfect for riding trails with varying light and coverage is fantastic.
Review: Just right - Large field of view , clear and light. Not so tight that it hurts and not too loose to keep slipping down on my 7 1/4 head. Worn over helmet straps . Originally bought for those overcast days or early morning into sunrise days for commuting . Pleasantly surprised ,can be used for full sun as well . Now only carry this pair for all weather. Big plus is the large frame , it no longer blocks my view with head tilted on the road bike . Of course they don’t look as good for double duty off the bike . Great price , good coverage. Only bit of discomfort at top of ear after long ride , as they stay put so you don’t have to keep adjusting them , so after three hours they “dig in” a little . As I say not a big problem at all . Happy with these

### ⭐⭐⭐⭐ The glasses are comfortable and tint, but the darkness is...
*by L***A on March 11, 2022*

I like the glasses and wear them for mountain biking occasionally. They are perfect for trails that occasionally run through the forest (dark areas). They're basically clears that will tint 'slightly' when in direct sunlight. These are NOT sunglasses and they do NOT get dark. As long as you know that, then they WILL block the wind and WILL slightly tint to reduce glare. They're great at keeping wind, dirt, and occasional sun glare out of my eyes... so I rate them at 4 stars.
