HI - bit of history - 37yrs old, was in 10 yrs, 10 yrs ago. I've been running prior to going back in the TA to get my fitness back and lose the accumulated fat of 10 yrs sedentary life (no excuse I know, but there you go - you can spare me the 'STABs don't need to be fit do they?' type comments too if you like - its pretty old now). Anyway - as the weather gets worse, I've moved to my Ron Hills and old long-sleeved smelly Helly, and have used a fleece gillet with it, but I have seen a few people out wearing these running jacket things - some flourescent, some not. Are there any real advantages to these? Or should I just save myself £50 and keep on with the HH and gillet? I'm only running a maximum of 2 miles, 3 times a week at the moment, but I am planning to increase the distance over the next few months. Cheers in advance for any constructive advice.
