I've been thinking of buying an expedition pack that would fit to my need on long trips. And at this time I am thinking of getting Osprey pack, probably Ariel 75. It is available on line, on my favorite website, it's on sale from USD278.95 to USD223.19. Something I really want to have but still expensive. I know this can wait, but really I will take one not now in the future and I know I can get it at a super sale rate, but someday.
