Osprey Ozone 75 Convertible
I was in doubt about ordering this product, since its very highly priced. Salomon for example has something similar (not the same) for half the price. All those doubts vanished after I received the product. Went on a 4 day trip with it, used the day bag as a laptop carry bag, worked out great. The harness for backpack carry can be removed to store extra stuff. Zippers are of high quality, has pockets for everything. Can´t fault the product. A small tip: it´s 75 L with the day bag included. Take that into consideration. The day bag is 18 L. Without it, it´s a little small for those big 2 week trips. Would recommend.
