If you're set on buying pre-made solutions though, the Proto Axis pro's have a fan attachment, as do JT's.

I've also heard good things about Cat Crap

Cat Crap is great - just you have to pay for it!

Thanks for the advice guys, tired the washing up liquid idea a couple of weeks ago and it worked alright for a bit but then started fogging again, the only real results i got was when wearing a mask with a fan. Tending towards the proto axis pro

Personally mate I would pay the extra fiver and get an i3 pro as I think they are comfier but it's your decision end of the day

All of these things work by creating a film over the lense which stops condensation.
washing up liquid, shampoo, saliva, all do that if you are in a tight spot, but something formulated for something industrial (or an exspensive/dangerous sport) might be better for example diving.

Personally i think you will love the proto axis, they are sooo comfy and intelligently designed, and they have a fan capabilities...
