This definitely has us feeling like sweater weather. This scarf is a mix of fleece/spandex/poly mix. It's a bit heavier weight than the flannels. It does have a stretch to it as it has spandex but might be a tiny bit thicker than the rest.
Material: Fleece/spandex/poly mix.
Scarves vary in sizes. Before purchasing please measure your pet's collar and that is your size. If they are fluffy or have a larger shaped head add about 2" to your collar size.
