Regardless of location of manufacture just take the time to inspect it in the store; tug, pull, turn inside out, use the zippers a bunch, tighten/loosen, ask them if you can put a dummy load in it in the store and walk around with it. If they really want a happy customer then maybe they will let you put it to the test, within reason, in the store.

Beware the "Made in U.S.A" label as meaning quality. Quality Control is a manufacturer's decision. The decision to implement ISO standards and maintain ISO Certification is strictly a company decision. Refer back to my first paragraph.
