F1 with batwings and hydration pack

Packed out two elk in one day with the f1, couldn't have done it without your pack. I originally thought the price was a bit steep but after using it I realized I was wrong. Thank you for making a well built and well thought out pack.

Solid pack frame

I don’t have anything similar in my experiences to compare this to, but so far I pleased with this pack frame. I’ve used it to carry four Helium 30” sticks, my platform, and backpack filled with miscellaneous clothes and gear. Weight gets well distributed. One day I hope to get deep enough in some National Forest land to have to pack a deer out and really put it to the test. Overall experience this far has been really good.
