Woolino Striped Sleeveless Baby Sleep Sack. This has been an absolute staple in our family! The lining is 100% merino wool which is known for body temperature regulation- not too hot or too cold. Not itchy. Outer is 100% organic cotton. Has a large zipper and button closures at the shoulder for easy of taking off, putting on, and diaper changes. There are also button closures under the armpit for a more adjustable fit as your baby grows. Please note the rips in the lining. This has been well loved but still has plenty of life left! Some minor staining toward the top from baby breath 😊
