The vents on this thing eliminate any fogging that creeps in. The only day I had any issues was a super cold -10 windy day, and after a simple lift ride cleaning and drying they performed well the rest of the day. The rimless lens also gives you a massive viewing window and you forget you're wearing them. All around great goggle.
I travel with this bag quite extensively and have absolutely used this as a carry on and it's almost always fit in the overhead. It really depends on how full you pack it. Worst case is that you'd have to check it at the gate, but I've never had them tell me to have it checked at security.
This watch has held up much more than I anticipated. It's gone mountain biking, canyoneering, swimming and seen more mud and dirt than most watches should ever have to deal with. It's also small, inconspicuous, and light enough you forget its even there. I hate bulky watches and this works for me better than any watch I've owned to date. It is also unique enough that many people compliment it and I never hesitate to recommend it to others. Buy it!
These are the perfect pair of cheap sunglasses. I've gone through a few pairs now and they are awesome for the purpose you'd expect: expendable. I've gone through 3 pairs of sunglasses since Spring (lossed in rivers, canyons, and scratched by everything under the sun) and have no issues hopping on and buying a couple pair at a time. They look cool, get compliments, and block the sun enough. That sounds like exactly what you'd want.
