I have used the old GG G5 pack for well beyond a servicable lifetime. Patching, reinforcing, and repatching...it finaly died and I replaced it with a 2012 Murmur, one of the first off the production line. The heavier Dynema fabric was everything the old spinaker was not. The straps are a bit narrower, but better built. The overall quality of the sewing was near perfect. This extended to inside seams which were double stiched WITH ribbon to prevent premature wearing. The pad pockets were well put together and "will" fit my normal, longer sitlite/thin pad...5 sections at a total thickness of just over 2-1/4".
This nearly maxes out the shoulder harness but, not quite...it works.
The torso strap is much improved, albeit, still lacks the virsatility of a full elastic one...my thoughts of perfection and I cannot hold that against a pack.
Unlike the G5, the bottom of the shoulder harnes is sewn through both layers and the core.
The detachable belt looks average. Since it will always be used, I will remove this complexity and replace it with a sewn in one. Again, personal preferance.
Overall, this pack should last 3-7 years without 1/4 as much effort as I put into the old G5.
A big well done.
Long Term review
I took the pack on a two week trip up the NPT. It carried well with the 23# starting weight...well over the design spec.
A couple quibles:
1) Front Mesh Pouch: This worked pretty well, but note that it was a bit loose. While the size is good when I placed my fuel bottle in it it sagged below the pack body. A bit awkward picking the pack up or setting it down. I had the feeling it should have been tighter.
2) The mesh workes well, I guess. I would prefer the old style silnylon on the front pouch. It caught on scrub and I put two small holes in it.
3) The bottom shoulder harness and torso strap was not well thought out. A longer strap fastened at the bottom and extending up to the top dynemaX shoulder reinforcement would be better by reinforcing the shoulder harness. This would prevent the stretching of the silnylon in this area. But, I WAS overloaded with food...
4) The shoulder harness slipped after a couple miles. The ribbon used for the bottom needs to be heavier to prevent the slipping. This continued throughout the trip and was NOT a product of overloading. After the first week I was withing carry-spec, but it still slipped. This did not really bother me, since I drop the pack on downhills(cooler, lower center of gravity) and lift it on uphills. Annoying on road hikes, however.
5) I used a 3 section nightlite pad as a frame that worked well. But I was within a couple inches of maxing the waist belt. Also, the wast belt was a bit narrow for 20#+ loads. After the first week it was fine.
6) The sternum strap (wrapped around the shoulder strap) caused some wrinkling of the foam/shoulder strap. Better would have been to only use the mounting strap rather than the whole shoulder strap.
7) I carry a SVEA 123, and where the pouch/OTT lid mounted caused some fraying of the silnylon. I place the 123 in the pouch (along with the cup and windscreen.) Easily repaired and probably a product of overloading with food, but, it did not get worse once it frayed. I believe the seam was a bit tight.
Mostly minor quibles and nothing to change my opinion generally. It carried the 23# easily and I often left the pack on for rest stops. 1 resupply at Blue Mountain pushed the weight over the 15# limit again (~18#.)
