I bought pants, long-sleeve top, helmet cap and socks. I recommend them - the helmet cap alone will make it much easier to keep your helmet liner sanitary.
I trusted them to allow me to wear my leather jacket rather than wear my synthetic jacket that allows me to remove the inner water-proof lining. However I was worried that this jacket would dehydrate me on the way to Middleton because I don't think this style of summer wear is meant for long-distance - 2 much perspiration evaporation.
The LDComfort gear removes moisture slowly, ie, it retains moisture in the outer layer and if u can organise a slight breeze by unzipping your leather sleeve a bit, then the stored moisture is circulated to create coolness. Another really neat trick is to pour some water down your sleeve (if you have the long-sleeve top) and the wetness will create a cool transference to your chest.
I didn't make it as far as Middleton, but the LDComfort wear got me 800km in a day. At no stage did I feel hot and the day we rode was hot. I also drank heaps of water at every op. However cramps caught up and spoiled my ride. Nothing to do with anything else but the fact that my heart meds are incompatible with Magnesium.
