I purchased the F1 with two batwings after extensive research on pack-out packs. Mainly based on how easy it is to load the meat up and get moving. Other systems require to much zipping and rearranging and seem to complicated. This is easy and can carry a lot of weight. Fitting it me was straight forward using the videos and the construction is top notch. Love that it’s modular and you can conform it to your needs. Also as a bowhunter I am completely comfortable drawing with the pack on because it is narrow and stays close to the body.
Holds lots of weight comfortably, like how customizable it is.
Excellent. I have taken this on two trips one overnight and one day hike. The frame is comfortable and provides a more rigid feeling during the hike compared to packs previously used. Highly recommend.
This system is very versatile and better than I expected.
I bought the 7500 first. It was to big so I got the 5000 and i love it its great. Only thing I would change is two extra straps and putting the badder holder in the center against the main frame
Haven’t used it in the field yet, but It’s great on my weighted trail runs,
Just got the mainframe with the Vapor 7500. Very satisfied with the quality and functionality of the whole system. Did a 15 mile overnighter loaded with about 60 lbs of gear for myself and my kids and the frame held the weight beautifully. Very comfortable and stable.
Well worth the money took a hike up the mountain about 2 miles somewhere around 45 pounds on, very comfortable love it.
The frame is great and matched with a vapor pack it’s on point!
