While the leash is new, it's supple and easy to handle. After being outdoors for the winter, the leash had hardened so much that most of the knots could only be undone with pliers or by cutting them open.
Therefore, it's not weather-resistant and therefore not recommended for outdoor use.
She bought the line to fasten the tarpaulin over my dinghy. The quality of the leash is poor! Abrasion resistance 0.0! UV resistance 0.0! Don't buy it!
