I know where you’re coming from, I’ve some good backpacks in the garage, not used them in 20 years lol !

I say if it’s good quality keep it…….even if your kids don’t want to use it to travel with, you might hit the road again and use it. My backpack was stolen a few years ago out of our car and I was devastated. I was going to use it on our next family holiday. Easy to stick one bag on your back and push another one when you’ve got kids. Leaves a free hand to hold theirs

I would use it if it is in good condition! Can’t see why not!

I have a friend who declutters regularly. If you haven’t used it fir months, get rid of it. Your daughters probably won’t want to use it. I saved a lot of baby things for my future grandkids. My kids aren’t interested, it’s old fashioned

If it’s in good condition I don’t see why they wouldn’t use it

If they are in great condition and you have space to store them, I say keep them. We still have ours from our overseas adventures but mainly because we sewed the badges from the countries we visited on them.
They come in handy i think. Especially if you travel with children.

Maybe save it and use it – may be a nice discussion about travel too?

We’ve got two Kathmandu backpacks that we bought 17-18 years ago. They are still in great conditions and I keep them in the closet. If you have space, yes, I’d keep them.

I think it is worth saving “just in case” since you say it is high quality, and they (or you!) might find use for it again. But perhaps be open to the fact that they may want to get their own equipment. I would not use the rucksack I used in my twenties now because innovations in technology have improved the design – lighter, more resistant, better ergonomics etc. But if when younger I’d had the option of borrowing a “good one” I would have done for some trips! For others would have preferred the cheap one I got that didn’t matter.
