My son has been using these for over a year -- they're nice pants with a number of good features. Some he doesn't use (leg zips), some which are useful (suspender buttons), and others which are great (innovative tightening-closing system that doesn't cramp stomach and waist).
They fit well, he likes that they're available in navy, and they wear well. Purchased the next size larger for when he grows out of these -- not sure whether a similar pant will be available then (the current RS and 85S pants have this feature).
