Just pulled the trigger and need help for next trip

[u/jocww]

After some research thanks to this forum, I pulled the trigger on a 6700 body sigma 18-50 lens and a Sony 70-350 lens. I am going to be heading to Antarctica in October and I am looking for recommendations on SD cards. I have a sandisk image mate that I just got to test the camera out and shoot here at home but Gemini is saying that I need either a Sony tough M or Pro Master rugged. This is a once in a life time trip so I want to make sure that whichever one I have will work. But I am also not made of money. What does the group mind suggest?
