I’ve worn these Field Jacket glasses on several ultra runs and in all my shorter races and trainings during 2 sunny Toronto summers. They’re great glasses in my opinion, with several features worthy of highlighting.

They offer huge coverage so there’s never a time I’ve had to squint, no matter what angle the sun. The eyes are always covered, and there’s very little chance of dust getting in. This is no doubt super helpful for mountain bikers, as well as those who suffer from hay fever (large glasses like this offer far more protection from pollen). I’ve also found it of benefit for city road running during the summer when heavy construction means the air is often extremely gritty (it’s said we have 2 seasons in Toronto; cold, and construction, and I’d concur that this is 1 accurate way of describing the city!).

An issue that effects anybody moving fast in the woods – or on uneven ground – is those few seconds of less than perfect vision that occur when you pass from brightly lit area to deep shade. This is a common occurrence when mountain biking or trail running. These lenses handle the transition superbly, there’s almost no adjustment period at all at you move from bright path to dark forest. I’ve always been able to keep my tempo and not have to slow down for fear of tripping on rocks and roots, because I’ve always been able to see where I’m going.

They’re also really comfy, sitting tight enough so there’s no movement whilst wearing them, but not so tight that I can’t wear them for 6 hours (which I’ve done often).

I really like the nosebridge feature which allows you to move the glasses slightly away from the face so as to prevent fogging. In these Covid influenced, hot summer day of wearing a mask, this helps immensely!

Finally, they’re hard wearing. I did get a scratch on them but that was because I put them in my running jacket pocket and didn’t realize that I had a coin in there as well, until 10 miles later (a rookie mistake, but one that I often make despite my advancing years and extensive experience of making silly errors!). It’s a testament to their hardiness that they’ve only sustained a little scratch during their time with me, actually.

The glasses are quite pricey compared to many sports glasses that are available but I believe they’re worth it. The clarity of vision they offer is superb, their coverage and feel is great, and that anti fogging nosebridge feature is genius.
