Use wool covers and soakers over fitted diapers or preflats.
Wool covers are made with a double layer of heavy Merino wool interlock in the body. The waist and leg bands use a lighter Merino wool interlock which is stretcher and softer.
Wool soakers have one layer of Merino wool interlock with a second layer through the wet zone. They use the same pattern as wool covers, but may not be suitable for overnight use.
These are very stretchy and fully lanolized. Hang to dry after use; wash only if soiled or starting to smell.
Hand wash only when needed and with wool soap (preferably lanolin enriched), gently squeeze out water, then roll in a towel to remove most of the water and dry flat on a drying rack.
