I want to take each of my children on a bike trip when they are old enough, but an having a hard time finding street youth riding gear. Helmets are easy to find, but jackets and pants are not so easy. I will likely buy one set of gear and when it fits will determine when the kids can go (might not get away with that on the helmets). Anybody been through this or have a good place to look. I would like to find textile so it's waterproof. Any help would be appreciated.
