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.

5.0 out of 5 stars Superior Quality and Performance
Reviewed in the United States on June 14, 2023
The SGT KNOTS Marine Grade Shock Cord is an absolute game-changer when it comes to securing and fastening items in any outdoor setting. This shock cord is a testament to superior quality and performance.

The durability of this marine-grade shock cord is exceptional. It is made from high-quality materials that can withstand harsh weather conditions, UV exposure, and heavy usage. I've used it for various applications, from securing equipment on my boat to creating custom storage solutions while camping, and it has never let me down.

One of the standout features of this shock cord is its strong elasticity. It provides reliable tension, ensuring a secure and snug fit for my gear. Even with repeated stretching and use, it maintains its elasticity and resilience, offering long-lasting performance.

The versatility of the SGT KNOTS Marine Grade Shock Cord is impressive. It is available in different diameters and lengths, making it suitable for a wide range of applications. Whether I need to secure a tarp, create a DIY gear strap, or tie down items for transportation, this shock cord delivers excellent results.

In addition to its performance, the bright colors of the shock cord are a practical touch. They enhance visibility and make it easier to locate and identify the cord among other items.

5.0 out of 5 stars marine grade bungee cord
Reviewed in the United States on March 28, 2024
Have been using this cord as a replacement for the cords from the costco auto tent I purchased long ago. i re-used the plastic ends and repurposed the cords to hold the sides that I made from cut down costco tarps. Well-made USA product, holds well, has not stretched after 3-4 months of use. Will purchase more cord when I need to replace the top and sides again. Please note the ends must be finished somehow to keep them from unravelling. Once I cut the cord to size, I melt the ends over a flame and then roll them between my gloved fingers and run them through the plastic and tie them off.

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 :).

Made my own set of adjustable bungees in various lengths by adding some adjustable hooks. Simple, inexpensive, and durable. I used some marine shrink tube to prevent the ends of the shock cord from coming apart. Excellent!!
