Ultra Trim Wool In Ones Ultra Trim WIO's are the bomb! These babies are perfect for summer, winter, and all in between. Great for you wool lovin mamas and ultra ultra TRIM! Similar to our PUL UT AIO's in style.. but made with wool jersey or flannel instead. The full coverage soaker system helps prevent soiling of the Wool shell. This will help keep poopy off the Wool and you won't have to wash the shell as often. Our Ultra Trims are a unique super trim system that was made specifically for those mamas who prefer a trim cut AIO with a low rise,full coverage in back, narrow crotch, and trim fit. They look and fit much like bikini underwear... but have all the protection and absorbency of a full cut. One awesome feature about the Ultra Trim's is that the side wings are NOT long.. they are short and trim thus then do not create bulk in the front the way longer winged side snaps do. NEW design accomodates chubby thighs!!!! They are adjustable with 2 rows of 5 snap settings, all hidden so that only soft fabric touches baby's skin.
