Document: This was a gift for our 3 year old granddaughter's birthday. She loved it. The only problem was after it was opened, there was a big dirty spot in one of the corners. We started to question whether or not this was a returned item and not new. We went with the more expensive bag, thinking it would be of better quality. I wanted to return it, but my daughter thought it would be okay. Hopefully it will come out after a washing.
My granddaughter loves this sleeping bag, and had to use it the first night she received it. I think it is a good quality bag for the price.
My daughter loves this sleeping bag! It's spacious, soft & durable. It's perfect for traveling. I'm pleased with this purchase.
My 3 year-old great-niece felt like a real Princess, snuggled in get "own" sleeping bag under the stars! Parents couldn't be happier!
