I am a 68 year old triathlete who works out in our local university (UCSC) pool. I have Raynauds syndrome and very slender (5’4”, 105lbs). I freeze in our pool which is kept at about 80 degrees year round. I would love to find a 3 mil shorty wetsuit but can only find 1 and 2 mil. I do fine if the water temp is 83. Don’t want to leave this gorgeous 50 meter out door pool. Any suggestions greatly appreciated
