Two questions
1. Are there any real functional differences between the new hipbelt that does not have the spacer mesh and the old ones?
2. I have noticed that on my hipbelt (with the spacer mesh) sometimes the fabric starts to rotate around the foam in the belt from the weight of the pack since the fabric is just sewn around the foam but not really attached in any way. I don't know if this makes sense. Not a big deal as usually at the end of the day I take a minute to put in back and it doesn't rotate far. I was wondering anyone else has seen this.
