Review on Kopack Waterproof Backpack: Perfect Business Compartment for Professionals by Darrick Dobbin

This backpack exceeded my expectations in every way. I use it to travel between jobs and it's been a great way to organize all my stuff. It is also suitable as a travel bag. Comfortably accommodates clothing, a 17" laptop, toiletries, accessories, chargers and a ballistic pad. Last week I had a downpour and both the bag and its contents were completely dry; Water runs off it. Even when fully packed, the bag remains comfortable to carry thanks to the padded and adjustable shoulder straps. I can easily access all of the bag's contents and there are plenty of external pockets making it easy to pull out used items. Two open side pockets on top accommodate a 1000ml Nalgene bottle. The build quality of this item is excellent. I've recommended it to everyone I've spoken to and I'm sure it will work for any purpose.
