Back pack is not bad , not bad at all . However it depends on how and for what you're gonna be using it . Its perfect for light stuff like clothing , or small light objects . But if your gonna put a lot of heavy objects in it , with weight more than 15 or 20 kg , I strongly advise you to reinforce the floor and sides of backpack with additional nylon or polyester straps (find a tailor or someone who has a sewing machine and knows how to use it) either on the inside , or on the outside (same colour straps on the outside if sewed correctly will actually look really cool ) .
Nice backpack, very large, must be durable, well add additional review later
