Kelty makes their "Haiku" in the 3000ci. size (3# 8oz.)... my wife LOVES hers. ( I paid $90.00 @ REI-Outlet 8 months ago for it)
$114.00 now @ http://shop.store.yahoo.com/mbstores-st ... nfrba.html
They also make a 4350 ci. Haiku. (3# 15 oz.)
( I have the same pack in the 5750 ci. size (3# 15 oz., same weight as the 4350) , I love mine as well & paid $129.00 @ Campmor 1 1/2 yrs., and 500+ backpacking miles, ago)
All of the Haiku line has the internal bladder holder (not yours, but one from which to drink
If you're looking to save some REAL $ ( I can't comment on durability) check out THIS pack...$ 40.00, 3# 2oz. !,
5700 ci. http://www.campmor.com/webapp/commerce/ ... rmenbr=226
Popular carries some Outdoor Products packs; you might get a look at it there, and they might "price-match" Campmor.... that is, if it suits your needs
Good luck !
