I bought some tri gear from Epix and am really pleased with it. Top quality. Went with the 8 mm chamiois and have done 2 sprints, one Olympic and a 70.3.
No worries at all on the run, will be using it for an Ironman in March.
They sent it to Australia for me. There is a long waitlist though as they are fairly busy.
Highly recommended

I have 2 of their one piece kits and really like them. both have the thicker chamois and it isn't noticeable on the run at all. The only problem i have found is that the zipper will chafe pretty bad if you don't liberally apply/re-apply some sorta body glide or vaseline.

Thanks, that's what I was looking for.
