It comes in 3 different sizes and I choose the middle one in 40-60 liters, it weighs at 2lbs 10 oz or 1.19kg. It is still able to carry loads up to 24kg though, which makes it a great value for the weight.
I love the fact the pack is super comfortable and has a lot of useful pockets. Only the top pocket seems to be a bit too small for my taste, i pretty much never really used it..
The pack has a great ventilation system, so if you are hiking in warmer environments it would be a very good option.
The biggest issue I had with the pack was on the Pacific Crest Trail when one of the straps broke. On the plus side, the Customer Support has been amazing and they sent me a brand new pack after just 3 days!
Let me know what you think
