I purchased this from Amazon to take advantage of Prime shipping.
Material is very high quality.
The design of the foam keeps air circulating and prevents my back from becoming a sweaty mess.
The straps are very rough at first, and we're quite irritating to my bare arms and hands when I was putting the backpack on. This improves with time.
The laptop compartment is very small. It barely fit my Alienware m15 R1, so anything thicker like the Asus Strix series or with large extended rear exhausts like subsequent revision of the m15 or the Lenovo Legion series most likely will not fit. These are all 15 inch laptops.
The water bottle compartment is way too small. I have no idea how they're fitting a 32 ounce water bottle as the specs say. A 23.7 ounce Arrowhead bottle barely fits and is extremely snug. I can't see how it can somehow fit a 32 ounce water bottle. Don't even get me started on insulated reusable bottles. It couldn't even fit a 18 ounce Thermoflask.
We're sorry to hear that the functionality of the Pack was lacking for you. We would be happy to assist you with a return if you would like.
The rain cover was already useful! lots of ways to organize things inside. Fits 15.6" laptop well. May have trouble fitting things that are too wide (front to back of backpack). Quality seems good so far.
