The Recon can add a bungee, so Borealis’s bungee is not replaceable. If you need a backpack with bungee, Recon is better than Borealis. Also, the Recon also with bigger water pockets. The Borealis can only barely hold a small Poland water. I have both Borealis and the Recon.
omg thank you for calling out the sternum strap is adjustable. I got one that I ordered online (for a specific color), after trying one on in the store. Had no issues on the store one, but the one from online had the straps SO LOW. I thought "did I miss this when trying it on in the store??" but PHEW. thank you for calling that out, i wouldve returned it and had no clue EDIT just checked my old TNF backpack, and that has adjustable ones too...AND I HAD NO CLUE. FOR 10 YEARS. omg
