Tom Cwrote a review of Arc'teryx Cierzo 18 Backpack - 1098cu in on November 22, 2011
So, this bag is killer. No doubt that the radness of this sack is one of epic proportions. I use it as my stuff-able day pack that goes into my bigger traveling bag. This a gnarly bag, the zippers are strong and stop rain, it is well structured, and the straps aren't that uncomfortable so long as you don't have 30 lbs packed in. I used to have the Marmot Kompressor stuff-able and it was not nearly as nice as the Cierzo. The Kompressor sat funny on my back and the top pouch zipper and draw string were an easy target for a thief on packed subway or bus, which always made me uneasy. The Cierzo sits well on my back and the double zipper pockets are well sewn in. There is also a little hanging pouch in the inside of the main compartment for your wallet/phone. The hip strap is nice too for extra support and the bag overall is hella light. I would buy this bag again any day. HIGHLY recommended. Hope this helps someone...cheers!
