I would suggest the contents of Doug's PSK. Most of us would agree that it contains the minimum equipment. I would suggest throwing in some water treatment tabs, just in case. The weight addition is negligible.

Not familiar with the Gossman PSK. What does it contain?

Definitely a good knife. Worth it's weight in gold, no doubt.
