I discovered this type of paracord and bought 2 different brands, Pskook and Power Paracord. I still have to try them out before I can say how well they work.
They have different types of sub-cords inside so you have to research which would fit your needs.
I don't want to go swimming in November to get a dead deer if he decided the best escape route involves a dog paddle deer version. Had a Caribou do that that my dad killed in northern Quebec. We were on an Island and had to wait until the guide decided it was time to check on us about 4 hours later. We were so far north that both the air and water were cold enough it didn't hurt anything.
