Loving this backpack! For a $30 pack it's really a deal. Definitely not the most high end manufacturing, but it's sturdy and I'm not worried about it breaking. The material looks professional and feels like a mix between backpack fabric and a rain jacket, definitely waterproof. It's incredibly spacious. In the picture included it has winter clothes for a three day trip, toiletries, entertainment (in this case a knitting project), a hat and a scarf, and my laptop, planner, iPad, and Bluetooth keyboard as Ellen as other miscellaneous items. It's definitely very full but feels strong and sturdy on my back. It sits comfortably and doesn't move around a lot, which I love because I use it almost everyday to bike to work (though it's not as full on those days). It's definitely not the same quality as an LL Bean backpack or a similar brand, but for less than half the price I'm very happy with it.
