To run in the evening and be seen

I use this strap to run winter late afternoon, when night falls. Two cuff, one attached to the arm, the other in the thigh, allow to be seen and attract attention; Indeed, by flashing LEDs and their unusual color (if however you choose something other than yellow or orange, which can be confused with street lighting or car headlights), it reassures armband wearer and notes by motorists (which always drive too fast and just as bad in town!)

The battery (CR2032) is easy to change, and bladder width is adjusted by the closure (clip) which can shorten the strap. Beware though, the original seams are very light and if you shake too (to prevent the cuff falls!), I found that the seam had let go! I suggest taking a sewing needle and a strong thread and consolidate all that!
