|Hi. I use a Swaddlebees large, a BabyBeehinds large, and a Wool In One from ABC (WAHM) cloth diapers on E-bay. They all fit the large Sandy's cotton and bamboo. I have to say, even though the BabyBeehinds is velcro( and I dislike velcro), it is the best one to use at night-no leaking-it has a double layer in the middle and is thick. Since I handwash all of them , the velcro isn't really an isuue in the wash. All the wool covers are undyed, natural. I just bought an Aristocrats to try. I only use wool with my Motherease and other cotton and bamboo diapers.
