请教Deuter的Paragon 75+15这款背包怎么样

Deute最新推出的Paragon 75+15这款背包，介绍如下：

Heavy pack loads demand everything from your backpack. To ward off fatigue the carrying system must excel in many areas. It must offer maximum load transfer yet be well ventilated, comfortable and not too heavy, flexible yet not unstable. The Deuter Paragon balances the ergonomic design with a finely tuned balance of flexibility and stability. A simple yet convincing arrangement of structural elements, V - aluminium stays and GRP stays, results in a dynamic carrying system.

What is noticeable about the Deuter Paragon is that it has been built on over 80 years of expedition experience
