In terms of size fits me at 1.79m height and 80kg approx Size L, M, however, would also fit.
The first impression is like having a box on his back and in comparison to the other two, he begins stronger shocks not nearly as well off.
The material adapts after a while when it gets warm at better than plastic but it was unfortunately already.
Moreover, in this model as compared to the other two lateral adjust the elastics around the seat better missing.
But compared to the Wave, he has the best shoulder straps, towards the Manis but lacks the upper chest clip for better grip.
In the area below 100 I tend in any case to the Wave about to Manis.
