Well the leathers, boots and gloves come with a 2 year manufcturing warranty - so the only way to damage those is wear and tear, but i would look at replacing them in 2 years anyway. And they recomend a new lid every 2 years or so! If you think that you will replace them in 2 years its only £350 a year, which is roughly 90p a day! DOne over 300 miles in 2 weeks in all my gear and it is all great - comfy, warm but well vented, easy to get on and off etc etc Will definately go back to them again. However did buy my chain, lock, cover somewhere else as they were on the heavy side for all the peripherals (spelling!)
