Review: nice quality cord - The cord has worked well on all my projects so far. The locks are a little weak and may not hold well under high tension. Otherwise, nice set.
Review: Great Shockcord !!! - Great product !!! Great size, thickness, for various uses and applications. I used it for winter glove keepers on coats, for a DIY hammock underquilt, and to make some old gym shoes into house shoes or slippers. The stretchability allowed me to use it to make a "net" on the outside of my pack to carry around a windbreaker or hoodie, if the weather got warmer, or have it available if the weather got colder or wetter. The cord locks have worked great, too. Easy to apply and use, even for kids. The color is basic black, so it works with most things.
