When shopping for a down comforter, the fabric matters a lot—it affects how well the comforter keeps its shape, stops feathers from leaking, and feels against your skin. Among many options, Warm Smile™ fabric (polyester for the warp threads, TC blend for the weft threads) stands out for balancing practicality, comfort, and value. Let’s break down its benefits and see how it compares to other common fabrics.
What Makes Warm Smile™ Fabric Good for Down Comforters?
Warm Smile™ fabric’s unique thread combination solves key problems people face with down comforters.

1. Stops Feather Leaks While Letting Air Flow
The biggest worry with down comforters is “feather leakage”—when small feathers slip through the fabric. Warm Smile™ fabric fixes this without making you sweat.
- Strong feather resistance: The warp threads (the ones running lengthwise) are made of polyester. Polyester is tough and weaves tightly, so feathers can’t push through the gaps.
- Good breathability: The weft threads (the ones running crosswise) are a TC blend (polyester + cotton). The cotton in this blend lets air move in and out, so you won’t feel hot or clammy at night—perfect for spring and fall use.
2. Durable and Easy to Care For
Down comforters are meant to last for years, so the fabric needs to handle regular use and cleaning.
- Won’t wrinkle or shrink: Polyester in Warm Smile™ fabric resists wrinkles. Even after folding it for storage, the comforter stays smooth. It also holds up well in the wash—unlike pure cotton, it won’t shrink or lose its shape.
- Affordable: Warm Smile™ fabric costs less than high-thread-count pure cotton. You get most of the benefits of pricier fabrics (like feather resistance) without spending too much.
3. Soft to Touch but Stays Puffy
No one wants a comforter that feels stiff or flat. Warm Smile™ fabric finds a nice middle ground.
- Gentle on skin: The cotton in the weft threads makes the fabric soft. It doesn’t have the harsh, slippery feel of pure polyester.
- Keeps its fluff: The polyester warp threads add structure. This stops the fabric from sagging over time, so your comforter stays puffy and keeps you warm longer.
