Tommy Caldwell recently switched to Edelrid back in 2016 because he believes that company creates the best climbing products suitable for his adventures. The Tommy Caldwell Pro Dry DT Climbing Rope is ideal for projecting hard routes whether they're fifteen pitches up or at a roadside crag, and it's fully prepared for alpine objectives as grand as the Fitz Roy traverse. Edelrid's Pro Dry treatment reduces water absorption to less than 2% as per UIAA Water Repellent Test, and it provides outstanding resistance against abrasion as well as water. Thermo Shield bonds the core to the sheath for better handling, eliminated sheath slippage, and longer lasting durability. Edelrid lap coiled this rope to come ready out of the packaging without any kinks or tangles.
