I use castelli free tri shorts. They have worked well for me in both full and half distances. Not sure about the chlorine resistance though.

De Soto Forza (4 pocket). Been using since 2005. Would not use anything else.

Actually used to run plain marathons in them too, and find them more comfortable on my tri-bike than any other short (ok, set setup for thinner tt shorts), but zero discomfort even on rough seal ironman distance rides.

To put into context, due to where I live, and custom/import duty rules I end up paying about 300USD for each pair yet still rely on them. Thankfully they last a long long time.

+1

Zero discomfort on the bike with these shorts and no issues running in them

if i may, i can suggest our Spider2 shorts; we've put a lot of attention to details and manufacture a tri shorts perfect for long distance racing.
