Halo sleep sacks for babies.

This is a bundle of 4 sleep sacks. 3 are Halo brand and the 4th is a different brand. All are used like a sleeping bag or a blanket for babies while they sleep. They have arm holes and the baby is zipped up into the sacks to stay warm (over their pajamas). Safer than using a traditional blanket. All 4 are in excellent condition and all 4 are size small. Birth to 6 months, 10-19 pounds. Go to Halo.com for more info
