me personally I'm a backpack person. More so because carry duffle bags drives me absolutely insane. If my bag is heavy, I would rather feel the burn of the straps on both shoulders than one lol because with one strap, I keep bouncing it from one arm to the other and it gets super annoying real quick. I am also a very short human being, and no matter how much the straps adjust on a duffle, I just can't seem to find a good length to keep it at, and then it awkwardly bangs against my legs as I walk and just about takes me out. and I can't help but walk like there's a stick up my butt lol I've always used under armor backpacks. allstar, college, and even now for work (I'm an ATC so the layers of clothing issue also still applies to me). I swear they are a bottomless pit. I use to bring so much useless crap I didn't need to competitions and still had room to spare for other stuff. During football and soccer season I normally carry an under armor top and bottoms, my rain pants and rain jacket, a quarter zip, a zip up, sometimes my other fuzzy northface or a hoodie, my hat, gloves, wool socks, hand and foot warmers, my binder in case I need to write up an eval, my personal belongings like my wallet, charger, etc, a lunch box of easy to go food, and my water. yep, I fit all that in my backpack. granted, I look like a turtle or something when i walk around, but it all fits comfortably inside and isn't heavy or awkward to carry. I really recommend investing in one. Mine came with a life time warranty too, which is awesome. The only sad part is, I don't think they make my specific one anymore :( I'll check it out and if I find it I'll post a link!
