Wool is amazing. It's breathable. It's a natural fiber. You can re-use it multiple times before having to wash it (yes, seriously, once every 2-3 weeks for washing is sufficient). Simply put, wool is an fantastic option for a cloth diaper cover. Many folks use wool covers at night to increase air circulation and also the absorbency of their nighttime system as wool can absorb up to 30% of its weight in moisture without feeling wet. But it's just as great for daytime and we drool over the adorable sloomb underwoolies. These are a super duper trim wool cover, available in a range of fabulous colors, that nicely complements any fitted or prefold you care to place underneath. We currently have the sloomb underwoolies in stock in birch, galinka, beeswax, fawn, ister and bloom. If these colors sound all cryptic, check out the color swatch on our product page. Final word? Sloomb underwoolies are adorbs. No doubt about it. Previous: Eucalan No Rinse Wool Wash
