Good morning and I will throw in a thought for you knowing you have already narrowed your choices. Nimrod Outdoors packs have been on my back for hundreds of hunts, thousands of miles the last 25 years and I continue to use the product line. The new carbon fiber back frame is absolutely incredible. Give them a look or give Nate the owner a call. They are made in the USA also, Idaho. Many of the others like Eberlestock and mystery ranch are based in the US, claim to be USA manufactured, but if you look inside you will find a tag from another country. Like Pakistan or Vietnam.
Just another thought.
For the finest hunting backpacks trust a system the firefighters working forest fires have trusted for decades. Nimrod Outdoor hunting backpacks are built on a customizing system to designed a pack specifically for you and your unique needs. We are the best-kept secret of mountain hunters.
