Fastpacking + tenkara (well, nymphing with a seiryu rod to be more accurate). This is the previous generation 30L model. No, not the lightest stripped down UL pack, but it is good at it's intended niche - moving quickly and comfortably. If your backpacking includes some running and loads under 20 lb, it's worth a try. I find it very comfortable, and the pouches on the front are great for organization (i.e. water bottles, fly boxes/tippet, camera/phone, sunscreen, knife, headlight, TP - really, anything small that you might need quickly and don't want remove the pack). Aside from backpacking (3-4 day UL trips), this pack has worked great as a travel bag / carry-on, and fishing pack when a long approach hike is involved. Downside is your back will get sweaty.
idoc72you are right ! this pack is absolutelly amazing for fly fishing ...
im however concerned about the total flatness on the back ... any thoughts ¿?

CollectiveMindI think the pack rides great, but your back will get a little sweaty. The perforated back panel fabric helps, but that's an issue with most any frameless pack. I got the old 30L to use as a multitasker that I could take out for a few days on the trail or cinch down for day use. I imagine the current smaller models (15 & 25 L) would make excellent fishing day packs when there's some hiking involved. Not the absolute lightest, but the easy-access organizational pockets on the front are outstanding for fishing.
