EUC storage bag for Uppababy bassinet. Velcro closure with two handles. Came with the Uppababy Vista set when I purchased. This is a lightweight bag/dust cover best use for storing your bassinet in your home between babies, in your garage, closet, nursery etc. or whatever your need be; not durable like the travel bags for airline travel sold by Uppababy. Material is most likely Polypropylene, similar to the fabric like reusable shopping bags some stores give out, but more sturdy/thick.
