These ended up being the best swaddles for both my babies! We tried Velcro swaddles and sleep sacks too, but these were the best by far! They fit snuggly but have some stretch so they can still move. The arms up position allows for babies to self soothe. The darker gray and the pink are 1.0 TOG and the green and light gray are .2 TOG. I found that the 1.0 TOG swaddles fit slightly tighter (have less stretch) than the .2. See the photos of tags for sizing. There is a tiny hole on the green swaddle and a tiny stain (most likely from reflux medicine) on the light gray swaddle.
