Color me unimpressed with the Stone Glacier. A pard used one on a goat hunt this year and it was epic discomfort for him. The straps on his pack wouldn't stay cinched and there was a lot of swaying going on. The shoulder straps and especially waistbelt seemed less than luxurious as well. We both had 100+ pound packs coming out and each had very different experiences carrying that weight. It was the first time I'd ever seen one of their packs in person and I was surprised at how unimpressive it was based on the great reviews I've seen them get.

I can say it's difficult to go wrong with Mystery Ranch or Kifaru. I've carried out literally tons of meat on the MR and multiple friends have done the same with the Kifaru packs. They flat out work and both companies have excellent customer service. Tip: Obtain and carry an extra waistbelt buckle. They only break when you have a bunch to carry from way back in, and the weather is bad.
