As is typical of Petzl lights, the Tikka Core is completely rainproof and highly reliable. Thanks to it being a "Hybrid concept" light, it comes with a 1250 mAh rechargeable battery, but if your trip exceeds the capacity of the battery, just grab along some AAA batteries (sold separately) and switch to using them once having run the battery dry. The light is easy to charge with a type B USB cable.
