What differentiates a dry from the non-dry rope is its ability to withstand wet weather conditions along with dirt and dust that comes with it. Although it’s normally recommended to invest in the climbing rope with a dry finish, you might not necessarily need this feature. Sure, it does take away some risks of potential harm when the weather is acting up, but if you know that you are not going to be using your rope in these circumstances, there is no need for splurging on one. Gym climbing, for instance, does not require you to have a rope with dry treatment, and the same goes for the sunny and cloudless weather. But if having a rope that will not get heavy from the absorbed water will give you a peace of mind – feel free to pick it over the non-dry rope.
