Materials
AeroChill Cooling Sorona® + TENCEL™ Lyocell Comforter
Cooling Shell
Crafted with a premium blend of 90% cooling nylon and 10% spandex, the double-sided shell is silky-smooth, breathable, and cool to the touch. With a Q-Max rating over 0.4, the fabric helps draw heat away from the body for an instantly refreshing feel.
Breathable Fill
Filled with 70% Sorona® fiber and 30% TENCEL™ Lyocell, this comforter delivers soft, cloud-like loft with lightweight breathability. Sorona® fiber helps provide resilient fluffiness and lasting comfort, while TENCEL™ Lyocell adds a smooth, breathable feel with natural moisture management.
Designed for Cooling Comfort
Together, the cool-touch shell and airy fiber fill help reduce heat buildup, support moisture movement, and create a lighter, fresher sleep experience for hot sleepers.
What's a Q-Max? It's the standard lab measurement for how cool a fabric feels the instant it touches your skin — the higher the number, the cooler the first-touch sensation. Anything above 0.2 is considered "cool to the touch." The AeroChill shell rates over 0.4, roughly double that threshold, which is why it feels instantly cool when you climb into bed.
Care
Designed for easy everyday care, the AeroChill™ Cooling Comforter is durably stitched to help maintain its shape, softness, and cooling comfort wash after wash.
Machine Wash Cold
Wash separately on a gentle cycle with mild detergent. Avoid bleach, fabric softeners, and harsh chemicals, as they may affect the cooling performance and smooth feel of the fabric.
Tumble Dry Low
Tumble dry on low heat until fully dry. Remove promptly and gently shake or fluff by hand to help restore loft. Do not iron or dry clean.

One night, plotted
Nothing to kick off at 3am.
Bed-surface temperature
Bed-surface temperature across one night.
10 PM · lights out
Cool the second it lands on you
The cool-touch knit starts at Q-Max 0.4 instead of waiting for the bed to catch up. You feel it in the first two seconds.
3 AM · the spike that isn't
Sweat leaves instead of pooling
Lyocell in the fill moves moisture out through the comforter instead of holding it. This is the hour most comforters start pushing heat back at you.
6 AM · still covered
Weight you keep on all night
No heat built up overnight, so the weight that felt right at 10 PM still feels right now. You wake up covered and rested.
Both SIJO comforters hold the band all night. AeroChill runs coolest at first touch; AiryWeight carries a little more gentle weight.

Plant-based Sorona® + TENCEL™ fill
Cloud-like lightweight
70% Sorona®'s partially plant-based fibres spring back wash after wash — light, downy loft that insulates without trapping heat. 30% Lyocell moves moisture out through the fill, which is why the weight never turns into heat.

Lightweight is 100% TENCEL™ Lyocell. All-Season adds 45% GRS-certified recycled polyester to 55% Lyocell for a warmer drape. Moisture passes out through the fill rather than sitting in it.

- KOKaila O.ReviewingAeroChill Cooling ComforterI recommend this productRated 5 out of 5 stars1 month agoLife saver with this summer heat
First - I only sleep on the SIJO linen fitted sheet for the past 6 years and SIJO’s FlexCool pillows. This summer heat is so bad that my house won’t keep the 68 temp and it was affecting my sleep UNTIL I got my AeroChill comforter. It has the same cool to the touch cooling feeling as the flexcool pillow and I’m obsessed!!! I may actually order a few twin sizes to use as blankets around the house!

Its thin but it has a good weight and i havent woken up hot since i switched from my old comforter
- MSMychelyn S.Verified BuyerReviewingAeroChill Cooling ComforterRated 3 out of 5 stars1 week agoSo insanely comfortable… but the size is not great
The weight and feel of this comforter is unbelievable— so soft and light, it’s very comfortable. However— the King/Cal King size just barely covers our king size bed (you could not reasonably use this size for a Cal King). Its weird size does not look great on the bed. We have decided to use it more as a throw on the bed because the smaller fit, making it kind of annoying to move every night to sleep then off the bed every morning. It is in fact smaller than the king sized throw blanket we were previously using. I should have double checked the measurements— but this is NOT a CalKing size comforter.
SIJO1 week agoHi Mychelyn! Thanks so much for taking the time to share your feedback. We're really glad to hear that you love how soft and comfortable the AeroChill Cooling Comforter feels. We understand your frustration with the sizing though. It sounds like the King/Cal King dimensions didn't work out the way you were hoping for your bed. We appreciate you pointing that out, and we're sorry the fit ended up being smaller than expected. Our size guide can be found on the product page which lists the dimensions for this comforter. Thanks again for the detailed review, and we hope you're still able to enjoy it as a throw.
