Lightweight Humidity Fighting Duvet

$349

Anti-humidity technology.

Designed with hot sleepers in mind, this duvet fights humidity with its merino wool layer and breathable cotton cover. Ethically sourced down provides softness and warmth, while sewn-in chambers prevent bunching.

Why you'll love it

MOISTURE WICKING: Made with an added layer of merino wool to naturally wick away moisture and prevent you from sleeping too hot.

BYE BYE BUNCHING: The sewn-in chamber design keeps the down fluffy and in place, so you can fall (and stay) asleep.

THOUGHTFUL DETAILS: Eight total loops (four in Twins) to keep your duvet perfectly aligned in its cover.

ETHICALLY-SOURCED: All-natural down you can feel good about.

Disappointing

"Too warm for summers (in a/c) in Philly and King size is much too large to fit into any duvet cover I could find, including the one that Casper sells for King size."

— Noelle (1/5)

Probably good

"Seems like a nice duvet. My wife claims that it’s made a noticeable difference for her, and she’s the hot sleeper so I guess it’s working. I haven’t noticed much of a difference personally."

— Jonathan (4/5)

The perfect bedding.

"It is gentle and lightweight, yet keeps you at just the right temperature and feels quite cozy. Very comfortable."

— Sandra (5/5)

Decent

"This duvet seems to be well made and in general I would recommend it. I would not however recommend it for anyone who sleeps warm or hot. I am generally warm when I sleep and I think this duvet will be great during winter for me. I will however have to find something cooler during the summer months. My biggest complaint is that I purchased this duvet for my summer bedding and it is much to warm for summer and it was advertised as such."

— Sean (3/5)

Cool!

"Full size was bought for son and he loves it! Says it is lightweight but gives him just the amount to snuggle into without getting hot!"

— Traci (5/5)

Does exactly as described

"Absolutely love it, so lightweight and cozy and doesn’t make you sweat."

— Sabrina (5/5)
