I hiked for 2 weeks in Portugal and Spain and I honestly hardly noticed the load in the pack ! Comfortable and well designed, pockets where you need them, rain cover built in, easy access to load and security where I needed it ?

Lightweight bag, however it is well-made and after 1 year of logical use, it shows no signs of wear and tear and of course remains completely waterproof.
The only disadvantage I find is that it does not have a carrying strap, you have to hold it in your hand.
