Familiarity: I've put it through the wringer
Have had my Bora 80 for 6 years of heavy duty use now and this thing is bomb-proof. I've had absolutely ZERO problems with it and have never bothered to use a pack cover as it really isn't needed IMHO. Carry heavy loads like a dream. As usual Arcteryx kicks ass. Pricey and worth every damn penny , just like everything I else I buy from Arcteryx.
