Sore wrist or tweaked finger that needs support, but you still can't stop climbing?! Metolius's 100% cotton tape may be the solution to keeping you on the rocks.
1½" (3.75cm) x 15 yards (14.25m approx) should last for many routes.
Also good for "taping up" for those gnarly Yosemite jamming cracks!
Zinc oxide adhesive keeps it in place and is moisture resistant.
PS. If it still hurts, more tape is not the solution - see a doctor!
