Bought this to compare to the Sabre 45. Lots of people struggle to choose between them as did I so summary below.
Sabre:
A bit lighter.
Bit more comfortable (more padding on waist belt).
More of a civvy look.
Round bottomed (so won't stand up when placed on ground).
Top pocket in lid opens backwards (toward the shoulders) so items easily fall out if open when lid is opened.
Taller but less deep front to back. Possibly making loads feel lighter as nearer back (not significantly).
Generally more rounded look and packing.
No molle attachments. Some useful strong loops on the back but horizontal not vertical loops.
Both bags use the same excellent side PLCE pouches.
One robust grab handle between shoulder straps at top.
Top lid is not detachable and sits snug to main body of bag. Neat and tidy but doesn't allow much to sit under it.
Can't attach anything to bottom.
Predator:
Bit heavier (but once filled you wouldn't notice).
Waist belt is not padded. Not a massive deal but may be an issue on long hikes. Sits well on my hips and I'm 6'3 and thin.
Military look with all the molle.
Flat bottomed so stands upright well.
Top pocket on lid is larger and opens toward the back of bag (not shoulder strap side). This means things don't fall out if open when you open the main lid.
Main compartment is deeper front to back so fits more in despite the same litre specification.
Generally squarer.
Molle loops and attachments everywhere to all surfaces including top and bottom.
Elasticated side pockets (these get covered if side pouches added but stop flat stowed items falling through).
Can add same PLCE side pouches as the Sabre.
Two robust grab handles front and back for better more balanced for vertical lifting.
Top lid is detachable and can be cinched down over anything (roll mat etc.). Adjustments everywhere.
Like I said both bags are excellent. Lots prefer the Sabre but I think I prefer the Predator. Bit heavier, more going on but to me the stable ergonomics and customisability are more important. Feels more boxy and robust too as the lid straps are attached more securely but Sabre users never complain about any wear and tear so just personal preference. Sabre looks simpler and 'cleaner'. Predator packs a few more litres into the main compartment (I've found this is perfect for my kit whereas always looking for space for my last item in the Sabre).
I use both bags for camping/bushcraft. Not a fan of modern style Osprey type bags. These two bags are extremely well made, rugged, practical and well thought through.
Cheap for the quality and compared to the competition. And in my view better than the competition for my priorities.
