70.3 Waco- Wetsuit or not wetsuit

Hey guys. I’m doing my first half and It will be the Waco one this October. But I have never use or buy a wetsuit because mostly of my races have been on hot seasons.

Do you think is necessary get a wetsuit for Waco?? Or just get one of those called skin suit that keeps you warm.

Also if you can let me know which ones are good brand options!!

Thank you!
