Yep, hi vis vests, they really work well. I ride into town without it, but headlight on, to do shopping, thats only a 400 yards ride at 20mph, last 100 yards 3mph! But any further, its hi vis everytime. You see reactions of cars users quite early, as the hi vis catches their eyes well. Also takes away the dependancy of using the headlight during a bright sunny day and letting the battery charge nicely. Its sleeveless, only cost £2 and has all the 3M reflective bands....definate life savers!
