Your choose from 4 of Metolius's best hold designs in a set of 12 random holds selected for bouldering. Naturals: With Flowstone and Powerline being two of our most popular collections, our design team set out to hybridize Flowstone's realistic rock styles with Powerline's sweeping features. The outcome was the Naturals, a choice collection of fun shapes and some new additions to boot! Colors: Yellow, Black & White Swirl Powerline: Bold, sweeping features and curvy radii dominate the Powerline's shaping style. One of our most popular lines, the Powerline offers distinct shapes which beautifully incorporate form and function. Colors: Blue, Black & White Swirl Solution: Perfect ergonomic forms with very subtle incut patterns which mimic solutional weathering in sandstone. Colors: Sandstone Greatest Hits: A nice, random mix from their different lines.
