This brush has a broad head and a narrow tip, making it great for all holds. The bristles are made out of boar's hair which is the BEST. You can attach it to your Pongoose stick clip to casually turn it into a stick brush for bouldering!
The 6.8 mm HollowBlock2 is made of 100% Technora® fiber for increased abrasion resistance and improved durability. It's gripping ability comes from the unique hollow-braid construction, for use as a prusik or Klemheist knot on ropes 7 mm or larger.
