The Pendleton National Park Pet Nappers are a continuation of Pendleton Woolen Mills long standing tradition of honoring America’s National Parks with a collection of distinctive park products. As a part of the National Park Collection, a portion of this sale will be donated to the National Park Foundation, the official charity of America‘s National Parks, to fund important restorative projects in the National Parks. The Pendleton Pet Nappers are made of polyester non-pill polar fleece with a quilted cotton canvas base and are filled with recycled high-loft polyester fill. The zippered, removable cover is machine washable for easy maintenance. Available in 5 sizes to fit most furry friends, you are encouraged to measure your pet to ensure an accurate fit. If your pet likes to sprawl out, consider sizing up.
