Yalid point.. weight depends on what parts you carry, between 3-10 lbs. It comes with a compression sack that brings all three bags down to a 10 inch dia. roll. The bag fits me well at 6'4" with clothes and boots on. When zipped together, all bags open with one zipper pull. All three bags would be too heavy for a kid, I think, but the patrol bag or intermediate bag by itself would be okay. And it would last a really long time; these bags are super durable.
