I can’t speak to comparing those two but the EVOC has the chainsaw holder on the back of the bag, so if you have a lot of stuff in the interior pockets, it will be on the outside of that. That being said, when I have a need for a chainsaw, I am typically not hauling other stuff in the bag. Also, you have to take into consideration where the blade sits, I position the blade away from my back, so it gives some room that it doesn’t hit your helmet, so you can put it with the blade close to your back but it’s going to be banging you in the back of the head unless the handle of your saw slides further into the bottom of the packThe Dakine 40l is off the table. Any input on if either the Evoc or Dakine 25l holds the saw closer to your back? And which has more of a “frame”?
Backpack works great. So much easier to pull the saw out compared to ruck sacks. One downside is that the hip “buckle” is more annoying to use than a regular clasp.
