Excellent pack. I paired mine with two bat wings and the scabbard. Can’t wait to put it to use
I love my F1 Mainframe. It's the foundation for a highly customizable pack system that is built to last. Thank you, Eberlestock.
Very comfortable, very strong, and just feels high quality. It was worth every penny and I would gladly purchase again if I needed to.
Great frame very adjustable. I fits me perfectly thanks
Purchased the F1 mainframe recently. Used it for a short hike, my vapor 7500 strapped to it smoothly. Frame is extremely comfortable with many adjustments. It carried my gear well. Strongly recommend!
