Familiarity: I've put it through the wringer
I've been using this bag for 4 years. I would rate it on its durably but I got to be honest, I have really beaten this on the rock. Even used it has a ghetto haul bag up the Washington Column. This thing has done from Rainier to Sierra alpine over the 4 years. It has many holes and rips but I suppose that is common with that kind of wear and tear.
This bags perfect weight is about 25lbs. Like the many other reviews, anything over that weight and the shoulder straps just plain hurt over a multi day trip. Having space for 55 liters means you can haul about 30-35ish pounds, however this is not pleasant with this bag.
Im in the market yet again for a new large alpine bag and I will not repeat with the BD Speed. Knowing that most overnight/multi day alpine climbing trip can be tough in the sub 25lbs range, I would prefer to have more comfortable shoulder straps to carry the 30+lbs load.
