I'm looking for a weekend pack (3000-4000 CI) that is reasonably light, without a bunch of geegaws and doodads, but must fit giants reasonably well. I'm 6'3", and have found it difficult to get a pack that fits. My last weekend pack, a Gregory Rock Lobster, didn't quite fit even though it was size XL. Can anyone recommend something that fits tall people? Do I have to get a custom fit?
