memaus03 Posted October 3, 2007 Share Posted October 3, 2007 I just came back this past weekend from a ride south. The ride home was only 500km but I suffered severely with overheating. Myself, not the bike. My first mistake was to trust those fellows in the weather bureau which led me to undertake the weekend trip with my ordinary jacket (without liner). I soon had all the vents open but continued to sweat profusely. I simply could not ride without the jacket although the temptation was there. I’ve had tar burn in my youth and still remember how painful it is. This brings me to the question that I would like some help with. That is to do with cooling options. I have searched this forum and read the responses and comments from fellow riders. I do however have some unanswered questions which I would like to put to you folks for comment. In summary of what I have read on this forum, there are two options open to me. The first is an evaporative cooling jacket/vest and the other option is a Phase Change Material jacket/vest. The first option seems the more popular but is restricted in effectiveness in higher humidity areas but is the easier ‘rechargeable’ option needing only ordinary water and uses airflow to cool you down. The second option maintains an even temperature and will work for 2 – 3 hours before the inserts require cooling. The cooling operation works with or without airflow. What I would like to know is: Evaporative cooling option: 1) At what percentage of humidity is the evaporative cooling vest considered to decline from being effective? 2) Does this vest/jacket wet your clothes either underneath or your jacket you wear over it? 3) Does it still work adequately behind the fairing and windscreen? Phase Change Material Option: 1) They talk about taking a spare set of inserts with you but how do you keep these cold/ready for use. Surely they run out just like those in the jacket? 2) How do you recharge them if you do not have access to ice or ice water or even if you break is not long enough to chill them again? 3) Is this still effective considering the inserts do not cover your whole body? 4) Do they really last 3 hours? Does performance decline from minute 1 or do they remain effective until the end? Ignoring the cost, which is considered to be the best option? I would not always have access to ice in small quantities and not sure how to maintain a spare set of inserts for later use. Any help or advice would be greatly appreciated. Thanks Link to comment
