The soft materials make it easy to wrap the stroller bags around the child's body. The filling is high-quality down, 90/10 grade 1, and the stroller bags are sewn with a unique box construction that prevents cold from entering.

It is the air between the down fibers that provides maximum insulation, and the stroller bags should therefore be shaken before use and stored in an airy place without compression. The outer fabric is windproof and has a water column of 3000 with BIONIC-FINISH®ECO.
