Fits great

It fits me great and I’m a large guy (6’4”,300). I’ve had issues with packs in the past not sitting correctly on my shoulders and hips. I haven’t tried it out yet but hopefully I’ll be packing some elk this coming October.

Excellent product

No question great quality. Using it elk hunting archery Mount Saint Helens. Little disappointed my son ordered the same product and received a hat and 3 coozy holders. Again wonderful gear!

Easiest shelf system and super comfortable

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.

F1 Mainframe w/ Vapor 5000 or Batwings

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.

Vapor 5000

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

Great Fitting Back

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.
