I use the Osprey kestrel 68 for week long trips, GF uses the Osprey Aura 65. Both work well, a little pricey but I'm counting on the whole lifetime warranty thing.
What I really like is the MEC Travel Light Top Loader we got last summer. Only weights 300grams, holds 19 liters and is super comfortable for it's simplicity. perfect for day hikes from our main campsite.
