Crux ChilL is a reusable hot and cold therapy pack shaped for climbers' fingers. Cool it to bring down inflammation and ease pain, or warm it to boost circulation and release tension in tired or strained fingers, with no bowls of ice water or kitchen mishaps.

Unlike improvised alternatives, ChilL won't split or burn the skin when applied directly, and its finger-shaped design puts the temperature exactly where you need it. It comes with a bag to keep it fresh in the freezer. For persistent injuries, always consult a specialist.
