Thanks everyone

I live 20-45 mins from my closest beach and s**** up before heading off, so that is not an issue.
My allergic reaction is so variable- sometimes I react, sometime I dont, and sometimes (like with the Invisable Zinc I am now using) it takes a year to suddenly react. The reaction is usually just itchy, and a bit red, but sometimes blotchy and rarely I get a crusty dermatitis.
So, any suggions how to 'test' for what componants I am allergic too?
I almost always react to the cheap brands (used to be able to use coles pump pack on my legs and arms, but not anymore).
I have used Bannana Boat Orange- which was effective but I got itchy after a year of use.
Oh yes, it was Kite Beach at Cocos- thats me in the distance, walking up after a long days kiting!
I guess I need to see if I can find sample sizes of the ones you have suggested above and try them for a few weeks.
The skins thing is probably a good idea too- you are correct they will probably be more comfy than kite pants flapping around.
Any suggestions on cheap 'skins' or variations and where is good to get them?
