Packing good so far.
Nice pack so far. I think I need to possibly stop into bozeman and get a great fit.. little tight in the shoulders but saved my lower... so far I'm liking it took it out for the first time since I got it over the winter.. had it loaded for close 70lbs for a trip I have planned into Idaho this season. And don't see myself having many issues with this pack. Very nicely built.

Pack is well made of course. The adjustability of the straps for different shoulder widths is amazing. Other packs just kill my neck and shoulders but not this one. We’ll see how it performs in 6 days!
