Last days I went through several websites that sells bags or backpacks with solar panels. It’s clear that the message that wants to transmit is ecological…” if you buy this bag you will show that you are ecologic friendly”.

But that’s not my first impression, if I meet somebody with this bag the first think I will have is that he/she wants to be “cool”…

But as I don’t want to keep with the first impression, I’ve decided to find out more. Following my first conclusions.
