OVers are made with a high quality natural cotton/spandex blend.  Like all fabric you must care for it to prevent early wear and tear.  

•Please remove your OVer from your car seat when snapping into your stroller or base. The bottom of all carseat have latches that can puncture through your OVer if it gets caught or snagged when snapping into your stroller/base.  These holes are typically found 1-3" from the bottom of your OVer and often are in groups of 2 or 3 (but sometimes can also just be by itself).  

*These holes or punctures are not covered under any warranty as it is not a defect or issue with the fabric
