For all i know, RSL is the most innovative company when it comes to badminton bag. Their backpack or carry bag are just vey good looking, compact yet stylish, and somehow able to fit plenty of rackets & items. Yonex, Victor, Lining, Kason, Wilson, Adidas, etc...are just producing very old style bags with different colors, except square shape bags which became popular since few years ago. Too bad these companies never really use their R&D for creative bag development, but they excell in rackets, shoes, & shirts.
Mostly I'll having a badminton backpack than badminton bag..because of....everybody will assume like I'm a really good badminton player when I bring along with my badminton bag...high expectation skills from everybody..maybe it will look alike a profesional badminton player..lol..
