The Best Down Comforters That’ll Keep You Cozy All Season Long

Filled with humanely sourced duck down, the Casper Mid-Weight Down Duvet is every bit as strategically engineered as its famed mattresses. A departure from traditional baffle-box quilting, the duvet's sewn-through seams create slim, rectangular chambers that hold the down in place, keeping the comforter at its peak fluffiness.

When I first tested this duvet insert, I immediately noticed two things: The outer shell fabric is incredibly crinkly but also very lightweight. Luckily, neither of these factors seemed to affect my overall quality of sleep.

The duvet's pillowy texture and rectangular quilting were also incredibly adept at facilitating airflow, making the piece feel very puffy but not too bulky at all. With its 600-fill power comprising evenly dispersed fill, it kept me feeling perfectly warm, though it never weighed down too much on me.

I've slept with this down comforter for far longer than our initial 1-month testing trial and am impressed with how it's held up over 3 years of use. I'd recommend it as my first choice to nearly anyone looking to upgrade their current comforter.

White down and feather fibers puff up the Parachute All-Season Down Duvet Insert. Its sateen cover (complete with corner loops!) and traditional baffle-box stitching hold the fill right where it's supposed to be, and its generously fluffed-up appearance keeps the sleeper toasty and warm.

Tester Scott Simone tested out the all-season version of this down comforter and found that it was really best for one season in particular. "This is, without doubt, a winter-use comforter," he says. "You can definitely feel it trapping air, so it keeps you nice and toasty. As the mercury rises, you'll want to swap this baby out for something with more airflow."

Filled with RDS-certified white down and feather fill, this piece feels fluffy but not heavy, helping sleepers maintain a comfortable body temperature. But if you are prone to night sweats or sleeping hot, we suggest investing in a bedroom fan or opting for another comforter in this list with a lower fill power.

Whether it's summer weather all year round or your bedroom just feels like it, the Pottery Barn Classic Down Duvet Insert is the ideal top layer to cozy up with.

Tester Sanah Faroke found that her sleep improved almost immediately upon using it, as it strikes the right all-season weight balance. “I usually go to sleep around 1 a.m., but with this duvet and the weight of it, I'm convinced that it's why I've been getting drowsy around 11 p.m.,” she says.

While she noted that this comforter is a little flat, its comfortable weight still feels “like a hug.” According to her, it seemed to puff up a bit more with use. Also, its 300-thread-count cotton cover is both breathable and not crinkly in the slightest.

The Brooklinen Ultra-Warm Down Comforter is a part of the brand's reviewer-favorite, three-comforter collection — but there are slight differences between each one in their materials.

The Ultra-Warm Down Comforter is the most luxe out of the trio, with its 750-fill power comprising 80% Hutterite goose down sourced from Canada. This means that although it's incredibly warm, it's also pleasantly lightweight since feathers tend to weigh more than down clusters.

This comforter is incredibly puffy and insulating, so if you have a temperature-controlled bedroom that you keep nice and chilled, this down comforter makes for a luxurious year-round bedding layer.

Scores of reviewers adore this down comforter, with one person saying, "This comforter is a game changer! I feel like I sleep at a hotel every day." However, some long-term owners of this comforter caution that it does tend to shed and create a lot of lint.

The Egyptian Bedding Luxurious Siberian Goose Down Comforter is incredibly fluffy, and the baffle-box stitching ensures that it'll stay that way for a long time. The lofty fill (comprised of 80% down and 20% feather fibers) is evenly dispersed throughout the comforter to avoid unsightly clumping or cold spots. It's also covered with a tight 1,200 thread-count Egyptian cotton shell.

Our tester Caitlyn Fitzpatrick tested this one out, and it far exceeded her expectations. “This comforter feels luxurious, like one that you would find in an upscale hotel," she says. "It makes me look forward to climbing into bed each night even more now.”

Though the comforter’s 750 fill power is warmer and less breathable than a middle-weight product, it's ideal if you like to be extra cozy while you sleep.

While some of the lighter products on this list surprisingly did retain body heat, the L.L.Bean Baffle-Box Stitch Goose Down Comforter is far more breathable than its lofty 600 fill power would suggest. According to tester Zarah Kavarana, “This comforter is perfect for all-year use, despite the fact that it's labeled as warm. It's hefty enough to keep you warm during the colder months, but still breathable enough to use during warmer months.”

Filled with RDS-certified white goose down inside of a 280-thread-count cotton shell, its Permabaffle gate system is advertised as keeping the fill in place, and Karavana found that it did its job to prevent clumping.

She found its balanced weight to be just the right level of cozy, saying, “Since using this comforter, I haven't woken up feeling warm or sticky. I sleep through the night without disturbance, and fall asleep far more rapidly.”

If you suffer from allergies and think that down is a dealbreaker, the Lands’ End Down comforter is for you. It contains down and feather fill that has earned hypoallergenic certification from the International Down and Feather Lab (IDFL).

While its 550 fill power is on the lighter side, our editor Stefan Vazharov thought this comforter provided more than enough insulation. "I found the comfort level to offer a perfect balance between lightness and coziness," he says. "The comforter did trap some air, but I didn't find it to be uncomfortable.” He recommends it as being a great choice for “any season except the summer” for this reason.

Vazharov noted that the 300-thread-count cotton sateen cover, complete with baffle-box stitching, kept the internal fill right where it was supposed to be.

The FluffCo Down Blended Comforter has something that no other product on this list has: a blend of down and Sorona fill. Sorona is a plant-based material that's lightweight, breathable, and insulating, making it the ideal complement to down fill — this blend also helps keep the product's price at a reasonably affordable level for its ample size.

This comforter has all of the must-have features like corner loops, baffle-box stitching, and a smooth 300-thread-count cover. Although the FluffCo comforter has a slightly crinkly texture, reviewers repeatedly tout its perfect cozy/cool balance as being better than anything they’ve tried before. As one person says, "This reminds me of sleeping in a cloud, and I wouldn't want it any other way."
