Looking for some kid's gear. We've got two boys (ages 1.5 and 4) and are doing more backpacking with them. Looking for the following:

-Backpack for the 4yo. Something small and light, with at least a sternum strap. Mostly for collecting sticks and stuff at this point.
-Kid size sleeping bag. We currently are using a down suit for the 1YO, but as it gets colder at night, either a warmer suit or sleeping bag would be good. Prob 24month size if it's a suit.
-Small cup. Prefer something with folding handles (titanium would be great, but open to options.

Also, always looking for kid's outdoor clothing for both boys. Let me know what you've got.

Thanks!
