Happiest Baby Sleepea Swaddle sack. Size small (5-12 lb). Zips up. Has Velcro straps to wrap around the arms and one comes up between baby’s legs. Snaps to open or close arm holes (can be used as swaddle or sleep sack). Rainbow tie dye color. Overall excellent condition. Velcro to wrap arms is strong. Strap between legs is a bit weak, but it doesn’t make any difference in function.
