Pack was more than expected. Had the mainframe with two bat wings and got an elk the first hunt I took it out. Packed out the head and one front shoulder without use of any rope. Very handy
high quality and durable.
Great frame helps haul a lot
I've done a couple trips with the f1 and Vapor 5k now and the pack was fantastic! One was hauling 6 gallons of water 4 miles to my buddies hunting spot, another carring 7 days worth of food plus everything I needed for the hunt and the last was packing half a deer plus all of my gear out. I highly recommend the pack.
Well thought out yet simplified design is great for endless configurations. Lightweight and very sturdy.
My husband definitely needed this upgrade! He is 6’2” and I was happy to find this size for him. It was comfortable for his long hike and hunt!
I recently purchased the F1 mainframe with the bat wings, 2500 cu. in. bag and rifle scabbard. I changed from a Lanner 5400. The fit of the F1 was far better and I like the modularity of the bags. I used it on a mule deer hunt in Wa. and it was great packing out. I just recently returned from an elk hunt in Montana and it was a joy to wear on long hikes. The rifle scabbard was a bit to get used to but once I readjusted it and got it set right it was great. I believe the F1 system to be a superior hunting pack. I would recommend the F1 to anyone who hunts.
The F1 with the Vapor 2500 is a lightweight, incredibly versatile pack that has become a favorite of mine. Picked one up with the rifle scabbard running between the frame and the Vapor. I couldn’t be happier with this setup. Very comfortable, the frame is very adjustable and makes fitting easy. I would recommend this setup to anyone looking for a good, all around multipurpose pack.
Fits fantastic on my large frame body.
Very modular for many needs.
Great info videos available to learn how to use and outfit packs as well as modular capabilities.
