For a $40.00 pair of goggles, these aren't bad! I have yet to test them on the field, but I just tried an exercise test to get me sweating while wearing them. Now, I also did not whipe the Revision Anti-Fog cloth on the goggles before this test! They did fog a little at first. Over time, it started to spread a little more as I sweat more. They did not, however, fog just while wearing them and standing around/walking (Before I exercised)
They have small slits at the side edges where the strap is weaved through, which allows a small amount of ventilation. I can sort of feel a breeze entering. There is also a gap, in the same location, in the foam seal, which may or may not aide in ventilation.
I'm not sure how I feel about the Velcro that hold the straps in place. They seem secure, but not as secure as having a solid strap. I don't for-see this being an issue, however
I will leave another review following field use of these goggles, which may determine if these goggles should be modified for ideal ventilation.
-As advertised, they are very low-profile! Excellent for you cover (hat) wearers out there; like me!
-Don't fog without exercise
-Comes with Revision's Anti-Fog wipe cloth (I have used this before, and it did help immensely in 109 degree Fahrenheit weather with Oklahoma's Humidity!)
-Comes with a little zip-lock bag to keep the Anti-Fog wipe cloth fresh
-Comes with a nice carrying case
-Velcro strap makes removing the cover-cloth easy
-Lens cleaning cloth
-Foam seems well-glued. Doesn't look like it'll give easily.
-Vents may not be open enough to properly vent, due to their location (blocked by strap?)
