Where to find durable go-bags, emergency kits, and survival kits?

Does anyone know where we can find solid, durable go-bags, first aid kits, or full survival kits here in PH especially ones that can withstand real disaster conditions?

I’ve browsed through Shopee and Lazada, but most of what I’ve seen doesn’t look very durable or complete.

If you already have your own setup, please share what’s inside or where you bought it. Thank you!

Please be safe!
