I have a pair of the Olymia, and ended up giving them to my son. The light color is a plus, but in every other respect I found them inferior to the First Gear. Why?
The waistband is elastic, with little adjustability. The front has ony a snap, not a hook, so isn't as secure, pretty much forcing me to use a belt, which is one more thing to buy, hook and risk scratching the tank. The rear pockets have big snaps: I don't want anything that I might sit on back there. The zippers are one-way only: to get something out of the pockets of my pants, I have to unzip all the way from the bottom. Instead of coming in short, regular and long, the Olympia are designed to be hemmed, but that means you need to pay someone to hem them, at extra expense. And it means the velcro closures at the bottom are very long, and seem to always be getting caught on things (mostly on the other leg) when I took them off or put them on.
All in all, I was very disapointed.
