Most double blankets are polyester-based. Listings commonly specify 100% polyester for textile and fill, and microfiber flannel fleece (often noted as 280 GSM) as a typical material.
Care instructions are generally machine wash and tumble dry. Listings often recommend washing with like colors and tumbling on low heat for best results.
Some blankets include waterproof or leakproof layers—such as a TPU lining or other waterproof membrane—and backing materials designed to protect mattresses, sofas, and car seats from spills and stains.
Adult wearable or novelty round blankets are described as large enough to wrap an adult. Available diameters listed in product descriptions include 47, 60, 70, and 80 inches.
Descriptions list many uses: wearable throws for napping or lounging, picnic or beach blankets, camping and travel throws, novelty or gag gifts, and pet or couch protectors.
Many novelty blankets are described as reversible or double-sided, featuring realistic, fade-resistant prints. Listings commonly note reversible fleece or double-sided patterns to emphasize print quality.
Waterproof or dual-layer blankets are described as having a waterproof membrane or TPU lining sandwiched between soft fleece layers. This dual-layer construction is presented as a way to block spills while keeping the surface comfortable.
