The lack of a frame in the goruck is a real disappointment. I tried a GR2 for a while, and did a few gorucks, but they just don't compete with modern packs. At least for me.
The Goruck have a sheet frame, I have plenty of hunting packs but if you do goruck events or Crossfit the frame doesn’t work. Cool if it doesn't work for you, but they are kind of built for the task. the plates make it pretty rigid as well.
My 2 cents... I've used the Atlas trainer for the past few years and put lots of miles on it. I've got no complaints with the quality of the build or any of the components - its both solid and still functions like new after extensive use. The system holds the plates tight and is stable on the body while rucking - the load is so close to your back that its pretty maneuverable even in weird situations like climbing over deadfall off trail. However, as someone who is 6'4", I have a significant complaint with the fit of the Outdoorsmans frame system. Despite situating the belt at the VERY top of my hips and cinching it down TIGHT, there is almost no way to get a disproportionate amount weight off the top of my shoulders. This is due to the load lifter attachment points and the lack of height adjustment there (frame is just not tall enough for me). I've tried everything from looping the lifter connections up over the top of the frame and connecting them from back to front, as well as trying to position the frame higher on the suspension. There's just not much adjustment available when it comes to torso length. Unfortunately, since I'm a bit taller, I can't get the frame to sit high enough and there's no way to get the suspension to put the remaining load onto the front of my shoulders vs directly on top. Its not a complete deal breaker for short 2-3 mile rucks and moderate weight of 60-70lbs, but the system definitely doesn't fit me particularly well and puts A LOT of unnecessary strain on the top of my shoulders vs transferring it to my hips. I suspect this system works great for the right body type (6' or less), but taller guys need to be aware that this thing may not fit them particularly well. Also, the belt system uses the old lateral pull design (pulling away from center) to tighten the belt - would be better if the belt used a more modern center pull design where the belt tights when pull tabs can de drawn forward and toward the middle of the buckle.
