I'm thinking of getting a set, mainly for towing the Goldie on Bribie this year & though I'm assuming they're UV treated, I'm going to keep them in an old tent bag I have, firstly to keep them out of the sun & secondly, making sure they're not too hot to handle after sitting up on the roof or in the back of my 'tilley all day. Perhaps they don't get very hot but "Out of sight, out of mind" also comes into play.
