Dolcino wraps are easy to care for and use. You can wash the sling with your regular laundry and either hang to dry or put in the machine dryer, although the fabric (as with any fabric!) will last longer if it is hung to dry. I have cut the sling about 4" longer than the stated length to account for shrinkage during washing and machine-drying, and it's fine to machine dry it at least once.
Secure but easy to access, a zipless pocket is big enough for the essentials.
Using your sling tail as a cover? A snap-on pouch/wristlet allows you to carry small items without adding bulk to the tail.
