Living in New England, we’re still in the late winter phase where it’s warm during the day but the evenings dip into the 20’s-30’s (Fahrenheit). This is the perfect down duvet. It’s lightweight and not too bulky. The loft is perfect to help with the cool evenings but being lightweight, I think it will be great to use all year long. I followed the instructions and put in the dryer for 10 minutes on low heat to fluff it. It came out perfectly fluffy and ready to go into a duvet cover. This is so cozy. I  love going to bed now.
