Purchased it long way back on oct 2014 . Sorry for reviewing this product very very lately!!!!!!!!
I received the bag in the period of 7 days. ( good, but not super fast delivery) .The delivery was good, and the packing of the product also good... I have been using this product since the last 7 months, and till now the bag has not been torn or has not got any holes and the stitching of the bag is of top quality. So far the bag has no problems...the backpack is very comfortable to carry.
if i carry some about of weight (not rock) in the bag, my back remains pain-free.
i would recommend this bag to all. 5/5 stars.
