I was searching for a lightweight muslin sleep sack for my little one. I combed through reviews, and the common theme seemed to be, It fell apart after a few washes. I took a chance with this brand, and I've been very happy it. It's soft yet well made. It has lasted through several washes, and the double zipper still works smoothly. I ordered the 6-12 month size for my tall 10-month-old (30"""""""""""""""""""""""""""""""""""""""""""""""""""""""""""""""") and it fits well with plenty of room to grow.
