"We replaced our down comforter with this and could not be happier. Really nice quality and keeps us nice an toasty without extra layers or being too heavy."
- Tina W."Love the fabric and really does feel cool to touch at night!"
- Lauren T."When I say this is probably the softest, most buttery comforter i’ve ever touched in my life, I am not exaggerating. It’s so cool to the touch, feels like the plushiest “Squishmallow-y” material, and regulates body temperature even with a duvet cover on. I would buy this 100 times again."
