I have a small pen light a friend gave me, he did not want it, I kind of thought it a little silly, however I have found it valuable. The lights went off here in Antigua, Guatemala for a short while. I store my pen light, candles, and lighter in specific places, never change. I need to find them in the dark.
The pen light is a good light, 99 percent of the time a flashlight is not need. I keep looking for a shake and charge small flashlight. The bottom line is a flashlight is too heavy for the amount of times I need it. Therefore this pen light is perfect. The switch is not a slide switch, this is perfect, normally a slide switch does just that, it slides and you have not battery when you need it. This pen light is difficult to keep on, I must continually squeeze it. It is just want I need.
I have this cork, pop in a bottle, fill the bottle with kerosene bobby, it is when there really is no electricity.
You might want to consider selling backpacks without actually handling them yourself.
You can use a dropshipper - you advertize and sell whatever the item is you want to promote - in your case, backpacks - and the dropshipper ships it for you.
This allows you to travel and do your thing without worrying about shipping and handling and storing merchandise.
It also cuts the amount of profit you make but you are free and unencumbered with stocking product.

They offer more than three million products from thousands of manufacturers, who will dropship items for you. They do charge about $70 for a lifetime membership, to access their database, which is updated and expanding every week.
I don't know if the backpack manufacturer you have in mind is one of their suppliers.
Anyway, I enjoy your travel adventures - You had the wit and wisdom to make money pursuing your travel avocation and I greatly admire that.
