i had one years ago and liked it, only thing was that they'd sewn the velcro on with the sharp stabby hook bits pointing towards your neck instead of the softer loops, so unless it was really tight it rubbed nastily, so i gave up wearing it! (should have got needle and thread out actually i guess and swapped the velcro bits around.)
but maybe they're better now, it certainly felt fine other than the velcro rubbing!
