I like the look a lot especially if the bags are colorful. You could also buy a dance bag. They're like duffles but cuter I think. And you can get them for either boys or girls although there's lots more for girls of course.

Personally, I think backpacks are so last year and the only thing a backpack does that's better is keep your hands free. But that's not a big deal

I think it kind of just seems like it'd get in the way with being soo big! alot of people at my school bring back packs and sport duffle bags but thats because yhey're all in sports! (x But you know, trends are trends (: I guess the smaller ones can be cute but I just don't get why people would want something soo big (x

What ever you like..I wear backpacks,colorful bags,on one side bag etc etc...it really depends what I'm carrying and what I wear. For me really BIG bags aren't functional,but they can look nice.

Thats what trending where I live. Its looks awkward to me bu I guess a smaller one will look cute and sporty. I'll stick wit my messenger bag :)

I think its fine to use one, as long as you have a reason to bring that big of a bag around like being in sports/dance/extra outfits for an event. Otherwise, theres other great bags out there that are so much better and possibly cuter! Duffle bags that arent that big are fine to use too, plus. Im the one who always gets thrown around by all those big duffle bags -_- haha!
