Test closures and access with a complete load, including water and emergency equipment.
02Inspect seals
Clean, dry and check coatings, buckles and closures as instructed.

Good to know
Does a raincover make a pack waterproof?
Not necessarily. Check its limitations and protect essential dry items separately.
Can I use any attachment clip?
Verify the manufacturer's attachment and load guidance before connecting equipment.
