1 .: The backpack offers plenty of space, I have a tent, clothing, food and much more easily transported in it. The many side pockets have proven to be very practical, you can small parts, which are needed fast access store, very good.
2 .: The material is of very good quality, the backpack has withstood the intense stress. Only on the right shoulder strap padding is slightly frayed, but that affects not a bit on the wearing behavior or another. The zippers are very robust, hold out a lot.
3 .: The backpack is very convenient when properly adjusted and gently on the back. The entire carrying system can be individually changed and adjusted depending on the weight of the backpack or height. I have up to 21 kilos carried around with me and had no problems. Only the load control strap (connection between shoulder strap and backpack) have slightly eased at this weight by itself. Overall, by the very good back padding very comfortable to wear.
4 .: The substance is to be to a certain degree also Rainproof in rain / recently, light rain all remained dry. For stronger rain I had built on the included rain cover. But as I discovered, this is much too small. Even if no sleeping pad is attached to the outside, it is likely to be short of a packed backpack. This some things were a bit wet. Therefore, the haunting Tip:
If rain is likely or possible, absolutely a great raincover also buy (z. B. by Deuter for 45-90 l).
So I can issue a slightly restricted, but certain buy recommendation for this product. If the trouble with the raincover not been 5 star would have been fully justified. Buy.
