Electronic devices are fragile and valuable. We recommend doubling up their protection by putting phones in waterproof pouches inside dry bags. Cameras can be placed in a small dry bag (5 L or 10 L) inside a large dry bag (30 L, 40 L, 60 L).
Ensure your bags are closed and check water resistance regularly before your session using a paper towel.
DO NOT SWIM WITH THE BAG OR IMMERSE THE BAG IN WATER.
