In reply to Removed User: I have a north face bag and a decathlon bag. Both 100 liters. My friend have a metolius 100 liter. We went on a trip to the states for 4 months with all 3 bags. After the trip we could not find any differences between the bags. They are a simple design and all made from hard wearing material. The Decatlon cost £30, TNF £100 and the Metolius £110. Get a decathlon if you can.
