I have only had the pack out on two rides but am mostly satisfied with its performance.
I wish the partition that separates the water bladder from the main compartment was taller. Also wish the shoulder straps were a little sturdier as well.
Overall the pack is doing what I had hoped, the back is open so I don't get overheated as easily and the weight is carried low around the hips as intended.
Time will tell regarding its durability...........

Big pack that doesn't bounce around.
Having that 4L bladder is so welcome on hot rides.
This is my second arctos...get the smaller one for short rides.

Love this pack! I was hesitant, thought it couldn't be all that, but it is. It took me just one ride to dial it in. Super comfortable, I cannot tell I am carrying 4 liters (4 kg = 8.8 lbs!) of water plus tools, snacks, etc. Simply amazing, plus my back gets air to help coole.
Also: Love that I can put my phone in the pack and still reach it. That is much better than MTB bike shorts pocket where it risks damage. Love how easy the bladder is to fill and put back into the bag. Love how the pockets are organized.
My only complaint is that black was the only color available. Would like lighter colors that don't get so hot in the desert sun!
