I have tried several packs over the years and I have come to know and love the quality and craftsmanship from Mystery Ranch. They have superb customer service and an excellent line of products for most pack/outdoor needs. I have a Beartooth 80 and a Pintler but was in the market for a slightly smaller pack without sacrificing its load carrying abilities. The Pop Up 30 fit the bill to a T. I recieved on a Thursday adjusted it to me and by Saturday I had it loaded with meat. The transition from a Guidelight MT framed pack to the Pop Up series was easy. It fits and feels the same. Im excited to have a bino mount on the pack as its often hard to hold 12 power binos steady enough to not miss the small movements. Overall its another great pack from them that I will continue to use along my others.
