Osprey packs are sewn in Vietnam. Nothing wrong with that, but it lowers the cost. Also, they've got volume on their side.
Pound bags are sewn by hand, one at a time, in the USA. And have top-notch warranty repairs. If you'll ever need them. They're pricy. And they're more comfortable and detail oriented than any other DG pack I've ever seen. I think that is important for a pack you are going to carry different ways (one shoulder two shoulders, by the grab handle) and you're going to pick up and put down 50+ times per round.
But yeah, spendy. And the best investment I have made in DG (except for a lesson).
Made in the USA and great customer service goes a long way! That makes sense. Hopefully I'll run into someone on the course with this bag so I can check it out.
