I have a ton of lumbar packs! These include two from True North Gear (a SERAC SAR and a Double Diamond), a Mountainsmith Tour with Strappettes, a Jansport Coltrane, a couple generic ones an fourteen (yes, 14!) Mountainsmith Vibe II's that I picked up from Woot for a project down the road.

While the "fanny pack" isn't very fashionable for urban carry it's not at all out of place on the trail or in the woods. It's actually very hard to beat a well designed lumbar pack for day hikes or hunting and fishing.
