Use the Thule Infant Sling in conjunction with your Thule Chariot stroller to keep your newborn supported and comfortable. This cozy sling has a hammock-like design that provides a comfortable reclining position for your wee one to nap the day away while you stroll through the park and meet up with friends for lunch. Thule included all the mounting hardware you need to install this sling in the chassis quickly and easily. The chassis' harness slides through the sling in three points to keep your baby snug and secure, but we wouldn't recommend using it for fast activities such as biking or running. This sling is compatible with the newer models of the Thule Chariot strollers.
