Shore Hardness: ~55A (very soft)
Sheet Dimensions: Each sheet measures 5.9 in (15 cm) wide × 27.5 in (70 cm) long, providing ample material for multiple resoles or custom projects.
Feel & Performance: GP1 is the softest rubber in the RATOM line, designed to deform and “flow” into even the tiniest surface textures. That softness translates to unbeatable smearing performance and friction on low-angle or polished holds.
Best For: Cold or indoor conditions where rubber needs to stay pliable. Climbers who prefer sensitivity and a glove-like feel underfoot will love it.
Notes: Because of its softness, GP1 can wear faster under aggressive edging or outdoor granite, but its stickiness is unmatched when conditions demand maximum friction. We do not recommend using GP1 outdoors in hot conditions due to how soft the rubber becomes under heat.
