Review on 🛏️ Premium Black Down Alternative Comforter Duvet Insert - Corner Tabs, Reinforced Double Stitches, Piped Edges, Siliconized Fiber Fill - California King Size 104"x96 by Sal Mattocks

Comfortable, warm, great price. Fiber feels very different from down - it's smooth, like conditioned hair, while down feels drier and has more internal friction. But it's warm and light, with little ties at the corners where you tie it to the duvet cover, and it fits a standard size duvet, so it meets all my duvet needs. Edit: 2 years later I still like it. I haven't washed it yet as it doesn't smell or change colour. I air it out a few times a year on a hot day and wash the duvet cover regularly and that seems to be all it takes. I bought a second one for my guest room and it was identical to the first.
