I cannot believe the difference that this makes. I wear glasses and in bad weather always have had problems with them steaming up.
I tried this, and the difference is amazing.
I recently came of my bike on the motorway while wearing these jeans, they worked brilliantly, I am lucky to come away with a story more than injuries. The trousers held up stopping me getting my skin ripped apart, the only bit the split was on the croch/arse area, I got a burn on my leg from friction but the trouser leg did not rip. Brilliant trousers and I can tell you for sure that they work.
Awesome bit of kit 30 mins to fit. Game changer.
Excellent quality gloves, very comfortable, have yet to try them in the wet but have high hopes
