Need a bag / carrying case for your child's nap mat to keep it rolled up neatly, protect it from the elements, and for storage when not in use? This one is perfect since it was designed specifically for those purposes. It's from the brand Urban Infant, which makes the popular "Tot Cot" nap mats that many people have bought for naptime use at daycare/preschool/kindergarten. This bag fits a rolled-up Tot Cot nap mat perfectly. Just unzip it, place the rolled-up Tot Cot inside, and zip it up again. The bag, which is made of PVC, is very lightweight, and water-resistant. It has a webbing handle in the middle for carrying the nap mat, and a hanging hook at one end that enables it to be hung inside a school cubbie. The handle has a plastic buckle that allows you to attach the bag to a larger bag/stroller/bike for transport. The zipper is chunky and comes with a circular pull tag to help little hands zip and unzip the bag. Other things also would fit inside this clever bag, which measures 22 inches long x 5 inches in diameter. You could put a thin, rolled-up blanket for picnics or towels for the beach or rolled-up artwork for transport between school and home. Since it's transparent you can see what is stored inside. This bag is NWT, packaged inside plastic that has not been opened. It was purchased directly from UrbanInfant.com and retails for $12. I have 2 identical bags to sell. To clean, wipe with a soapy sponge and air dry.
