Me, I have a black transpack backpack with:
My Riedell Elite Royal 900 skates (2003 model I believe, and with almost four years on 'em), blades covered in black soakers with seatbelt-like material on the bottom
Folder for coach's notes and other materials (pen, blank paper, recent test sheets, step patterns, USFS MIF rulebook, latest program music CD)
Old, faithful translucent blue glitter hard guards clearly marked with my maiden name
Phillips head screwdriver
Lock for the rink's locker
Travel-size pack of facial tissue
Two matching pairs of gloves
Hard (rollerblading) wrist guard
Knee/Elbow pad (it's whatever I need it to be, when I need it at all)
Combo hip/knee pads I made from scratch to imitate those pricey Clear Clouds, fashioned from their patent filing drawings and 3/16" Akton gel padding material I bought at a fraction of the cost
Athletic tape and foam liner tape for it, just in case...
That's it! That's enough.
