Good belly button ring?

I am going on a service trip to Alaska in July. I have a belly button piercing that I had done in December-Januaryish. The only ring I have that is NOT dangly, is a surgical steel one that occasionally irritates my belly button. I am going to be living in a tent for like a month, doing hard work, and will not have the ability to shower often. Can anyone recommend a good ring that would not irritate my piercing for during this period.
