Cold weather flexible 30 amp power cord?

Is this what you are looking for?

Here is oneFlexible Cord

The yellow Marinco cords remain flexible when cold. I have both a 50 amp and 30 amp Marinco cord.

First, thanks for all replies.

dalenoel, that cord looks like a possibility. Have you used one like it?

Ranger Smith, I saw that cord and it looks like it would be flexible in cold weather, but I don't think that company has 30 AMP cold weather flexible cords.

BB_TX, hello to a fellow Texan. Somehow we must have different cords. I bought a 30SPP.RV cord and it is really not very flexible at all in the cold weather we have been experiencing lately (say 40 degrees). I know Marinco is reputable, but this time they did not deliver to me what I thought I was going to get. Or maybe I ordered the wrong one?

I should say that my Marinco cord is flexible in the cold compared to the black cord that came with the trailer. Not to imply it rolls like a rope.
