Also, how can I stop my hands from getting shredded to bits (they seem to take ages to heal and then they just crack).
If the flapper isn't major you can just put a bit of finger tape over it when you climb.
Dont forget the chalk bag, chalk bucket, finger tape, toothbrush on a stick, toothbrush not on a stick, guidebook, bouldering mats, shoe cleaning rag, beanie collection. Did I miss anything?
