I have the Onester and the Sleepster for my son and love them both. The Onester I have in the River Blue Anchor pattern and features short sleeves, no pants and snaps at the crotch. The anchor blue print is 100% brushed cotton for a soft and worn in feel. I’ve washed both pieces and the cotton only gets softer after washing. What I love about this collection is the fact that the front paneling of the clothes feature a double layer of fabric. The idea is it keeps the baby warm while they are 0-6 months because babies spend so much time on their backs at this stage. The one layer of cotton on the back side of the onesie allows the baby to avoid overheating. I also have the mbaby Sleepster for my son, which has a convertible foot, so he can play and wear footless during the day and can wear as pajamas at night to keep his feet warm. You simply uncuff the pant and roll the fabric over the feet and snap to fasten closed. This is also idea for those of you that have tall babies that tend to grow out of their enclosed onesies. We have the Sleepster in the pinstripe aqua pattern and it features an adorable ship’s wheel on the front chest. The pattern on the inside is white with blue anchors, which you can see when you roll up the footsie portion and wear as pants.
