Hello Triathletes

What neoprene wetswit you recommend me to buy?
I have been a pool swimmer all my life and I have had to quit because of respiratory problems with chlorine

Now I have started in open water and with triathlon, and the neoprene that I have is not going well, it is very hard on shoulders and maybe it floats too much for me.
I would need something more for a swimmer, with good shoulder flexibility and good floatability but not excessive...
And if it's not very expensive, better hehehe

Thank you!!!
