The Visto Triangle mounts to the two rails of a bike saddle using stretchy reflective paracord and a cord lock. It makes a cyclist far more visible to cars from behind (both day and night). The triangular hole in the middle lets a rear light shine through and improves airflow (so it's doesn't flap around at speed).

These are handmade in Oakland, California with reflective vinyl and 3M Scotchlite. This triangle weighs roughly 10 grams and allows for a tight zero dangle connection or an extension of up to 3 inches or 7.5cm (in case you want to mount it to a bag/rack). Every cyclist needs one of these for each of their bikes--it's a passive safety system.
