The patented bundleme conveniently and securely fits into either three- or five-point harness systems of car seats, strollers, joggers, or bike trailers through reinforced openings at the back of the bunting. Lined with soft, warm shear ling and a fleece outer shell, the bundleme features strong double zippers that run the length of each side for easy temperature control: unzip and roll the bundleme down as the weather warms, or zip it up to keep your child cozy. The top shell can also be zipped on or off for easy indoor-outdoor transitions. It's even machine washable, and comes in two sizes: one for infants (0 to 12 months), and one for toddlers (1 to 3 years).
