New and Assistance Required

Hello,

I have completed one super sprint this year (my first one ever) and have another planned towards the end of the year, both pool swims. I haven’t bought a Tri wetsuit and am concerned about open water, but wondered if a Tri wetsuit supports buoyancy in pool swims please? Also, I assume Olympic distance Tri are only in open water?

I am likely to ask hundreds of questions so apologies in advance and thank you for your patience with someone new to this sort of thing.
