5.0 out of 5 stars Don't let 1/4 inch put you off if you think you need larger diameter - sailors take note
Reviewed in the United States on May 30, 2024
I am going back for my third 100 foot reel of this cord.

The UV resistance has been excellent aboard my sailboat where I use the cord for retention of my flag halyard to the toe rail. This is my most UV exposed application and it has held up very well in weather 24/7/365. Even the color (red) has held up. Very pleased with that compared to other cord I have used.

I highly recommend rolling your own bungees (second picture). There are any number of hooks available on Amazon in various configurations. You can deal with almost any bungee related use case if you make your own plus it is way cheaper and way more configurable to your specific needs.

I had typically used 3/8" cord and was a little reluctant to go with 1/4" cord (Sgt knots is out of stock on 3/8) but I was very pleasantly surprised with the robustness of the 1/4 inch. No problem for my applications.

For example, I decided to make an anchor snubber (first picture) a couple of weeks ago and had a bunch of the 1/4 inch bungee sitting in the garage with nothing to do. Normally a snubber would require two strands of 1/2 or 3/4 bungee to deal with a 7500 pound sailboat with chain rode. I decided to use a big loop of four strands of the 1/4 inch resulting in a combined 8 5 foot strands of bungee to provide about two feet of "spring". This worked perfectly at anchor in up to 20 Kts gusts of wind. So, for you sailors out there, this stuff is the bomb. Good UV performance and quite robust.

I checked the stretch factor - there must be a technical name for this - and found the cord would stretch comfortably from four feet at rest to six feet at pretty full stretch. You can do the math to figure out what that means for your application and your cord length. As I mentioned, the "resistance to stretch" ls excellent based upon my experience with my snubber. Again, there is probably a technical term for this too.

Reviewed in the United States on June 22, 2024
Used this to put through grommets on bottom of curtains I hung in a screened Lanai to keep the wind from blowing them. Worked very well even in a strong wind! After a couple of years they still perform like brand new, no loss of elasticity!

It works perfectly for what I'm using it for. Not to firm, just the right amount of stretch for my application.

Reviewed in the United States on July 3, 2024
So far, so good. I use it for restringing my zero-gravity chairs, and it's nice, strong bungee cord with a solid outer layer. No issues yet, and my chairs stay outside all the time.

5.0 out of 5 stars Holds up very well
Reviewed in the United States on May 20, 2024
We us this to to tie up our cat in the yard while we are out there with her. This is really good ,allows her to stretch and jump, with out pulling on her. She loves being outside with us. It holds up really well in the weather, as we leave it out all the time. However it doesn’t fair well against the lawn mower blade :).
