This is such an amazing travel bag, it's lightweight, it folds so it takes up very little space when not in use, it has a shoulder strap, it's EXPANDABLE!, and it comes in a rainbow of colors!!!
If your budget allows, check out the chic canvas one called Cricket, it is better made and will last longer lasting than the Le Pliage version, although not expendable and also has a higher price tag.
Go check it out and tell me what you think!
