I'm finally taking the plunge and am starting my RTW in 1.5 weeks.

Has anyone heard of the PacSafe? It's this security net that you put around your pack so people can't cut open your bag like it's a pinata and steal all your candy.

It's about US$60. Does anyone recommend this? Is it necessary, or just another thing that I'll wish I hadn't brought along?

Happy travels!

Wow, this question has been coming up a lot lately, and has led to some good discussions that should help you out:

PacSafe - Good, Bad, or Just Ugly

How cheap can you go? (there's some stuff on PacSafe farther down the page)
