Getting a good night’s rest can be difficult when your duvet causes you to overheat. To help you in your search for the best lightweight duvet inserts, I’ve gathered a list of the top options on Amazon, based on three main consideration: fill, shell material, and stitching.
Whether you’re looking for a duvet insert, choosing the right fill will be an important factor in your decision. There are three common fill types: goose down, alternative down, and silk fill. Down alternative made from materials like microfiber and polyester tend to be much more affordable, less likely to aggravate allergies, and more suitable for all seasons. While goose down can provide more warmth and loft, you’ll want to stick to a fill power of 600 or less to keep the duvet lightweight. The higher the fill, the heavier and warmer it will be. For hot sleepers, a silk-filled option can regulate body temperature and is super lightweight. However, silk bedding often has a much a higher price point than other options.
When it comes to the duvet’s shell, your options include polyester, microfiber, cotton, or a blend of materials. Polyester tends to be moisture-wicking and often budget-friendly, but it may not be as soft or breathable as cotton. Microfiber, which is typically made from polyester or a blend of polyester and nylon, on the other hand, is breathable, durable, and wrinkle-resistant.
Depending on the type of fill, duvet inserts will usually have either sewn-through or baffle-box stitching. The former is a more affordable option, but the latter is better for real goose down options in particular, as it allows more room for the down to achieve its full loft. Both will help keep the fill evenly distributed.
Read on for the best lightweight duvet inserts to keep you cool and comfortable all night (and they work especially well when paired with a cooling duvet cover).
1. The Overall Best
What’s great about it: For a reasonably priced pick that’s suitable for all seasons, this is one of the best duvet inserts on Amazon. With microfiber filling and quality stitching to keep it in place, this duvet is a lightweight option that will still provide sufficient warmth on cooler nights. Made out of a microfiber shell, it’s both breathable and hypoallergenic. It’s even OEKO-TEX Standard 100 certified, meaning it’s been thoroughly tested for many harmful substances. Designed with tabs on each corner, your duvet cover will stay securely in place, if you choose to use one. This pick is machine-washable and can be put on a low tumble dry cycle.
What fans say: “This was such a good buy! I’m impressed with the quality for such a low price. It is very light weight. I’ve washed it several times now and the material is not beading or pilling at all. Color is bright and true to pictures as well. Very pleased. It is better than what I expected at that low of a price. Don’t get me wrong, it’s not amazingly luxurious. But it’s a great quality for the price.”

To maintain this duvet, spot clean it with cold water and hang it to dry, being careful to avoid any prolonged sun exposure. This duvet should not be bleached or tumble dried.
What fans say: “I purchased this duvet because I like the weight of a cover in the summer but was getting to hot with a quilt. This is a great product!
