long sleeve transitional swaddle sleep sacks

Our long sleeve transitional swaddle sleep sacks are the perfect in-between solution for little ones moving past traditional swaddling but not quite ready for a standard sleep bag. Designed with a snug, age-appropriate fit in the torso to help ease the Moro reflex, each sack allows plenty of roomy comfort at the bottom for the natural frog-leg position babies love.

Finished with cozy long sleeves for added warmth and comfort, these thoughtfully crafted sleep sacks also feature our game-changing WONDERZiP® technology—making midnight diaper changes quick, quiet, and effortless so everyone gets more rest.
