1. Buffy Cloud
Recycled fiber fill that breathes well. Hypoallergenic and eco-friendly. Sleeps cool enough for hot flashes.
2. Brooklinen Down Comforter
Ethically-sourced down with lightweight, all-season, and ultra-warm options. 1-year trial.
3. Quince Down Alternative
Budget-friendly microfiber insert with surprising quality at the price point.

Down vs down alternative
Down is warmer and lighter but can trigger allergies and traps heat. Down alternative (PrimaLoft, recycled fiber, microfiber) breathes better and is hypoallergenic — usually the better pick for women who run hot.
Get the right fit
Buy a duvet insert 2-4 inches larger than your duvet cover so it fills the corners. Look for corner loops to anchor it inside the cover.
