Its a cute bag - but you know what I am worried about?
It looks like those seatbelt material - so when you put it up against you on your body it is going to make you really hot because it traps the heat in I think - cuz I had a Diesel bag before - its made of multicolour seatbelts - i took it out one day and it was really hot - I was walking to my campus at school - it was like a 5 minute walk and I was already sweating all over the place, and I don't usually do that - I think that material really traps the heat in... good thing I was able to take it back the next day
So I would not really recommend that material for summer.. but if you like it - and can withstand the heat - go for it!
