I have had this bag for about 5 yrs-cant fault it,tough,sturdy,does what it says on the tin. i had a smaller version with the freeflow back system also,so im use to it,although you do loose a small amount of space inside the sack due to the shape of the carbon fibre whatsitt thingy,but its worth it for a sweat- free back.the only way to improve the bag would be to include a wand pocket,to stow walking sticks as opposed to the ice axe carriers,but thats nitpicking
