I like to go hiking a lot and we always tend to take a lot of bags. Things can get really heavy sometimes and any little bit of extra weight is really a hassle. This backpacks that is extremely lightweight it's like carrying nothing extra at all. It seems really sturdy and I've used it a few times so far with no problems at all. It is a typical backpack size and so it can carry the same amount of stuff as my other backpacks yet it weighs almost nothing. I like that it comes with an extra little bag to keep a few things extra separate from everything else. If you are a hiker or a biker or even a mountain climber this is a great backpack for you it is virtually weightless and still somehow very sturdy. Overall it's really great and I love it
