ESTARER Laptop Bag Shoulder Bag Men's Canvas for Work Plain Grey

Would two laptops fit in this together if I'm happy for one to be in the non-padded section?

Will this fit a full size keyboard aswell as a laptop

Lightweight is important to me. Is it really only 299g (13inch model)? Thanks

Are the leather parts of this bag real leather? Asking because I'd like to know if the bag is suitable for vegans.
