Don't hesitate - these pants like it rough. Take them and climb as much as you can ;-). The fabric features a composition of Cotton and Elastane. Cotton fibers provide the required ruggedness. The Elasthane content along with a regular cut and an integrated gusset enable great freedom of movement - however tricky your moves might be. The classic design even makes them a trendy companion for many non-climbing activities. Contrast colored inserts freshly complete the style. Not to forget about the laterally attached cell phone pocket that comes with an integrated mount for boulder brushes. (brush included).
