Product Insights
The Boreal Prestige Duvet Certified Responsible Down by Simons Maison delivers winter warmth equivalent to 725-fill duvets using 600-fill duck down, achieving 20,700 cu in loft in queen size. Its sewn-through box stitch prevents fill shifting, reduces overheating, and lowers cost but creates minor cold spots at seams. The 34.5 oz fill feels heavier than equally warm higher-fill down. Responsible down lacks a specified certification standard despite Montreal manufacturing. At $399 CAD, it matches a competitor's price but without trial or certifications, requires cold washing and tennis-ball drying to maintain loft, and is best for winter only.
Verified claims
- Fill power
- 600 fill power yields 20,700 cu in loft in queen, matching 725 FP duvets.
- Warmth
- Winter-warm but too warm for summer; box-stitch reduces overheating.
- Durability
- Box-stitch prevents fill shifting; wash at 30°C and dry with tennis balls to maintain loft.
- Weight
- The 34.5 oz fill feels heavier than equally warm higher-FP duvets.
- Comfort
- Buyers report the duvet feels fluffy and cozy.
- Care
- Preserve the 600-FP loft by cold washing and tennis-ball drying.
- Box stitch
- Sewn-through box-stitch prevents fill shifting, reinforces shell, and lowers cost.
- Cold spots
- Seams without fill create minor cold spots, making the duvet slightly cooler there.
- Certification standard
- Responsible down fill lacks a specified certification standard.
- Value
- At $399 CAD, the queen-size price matches a competitor that includes a 120-night trial and certifications.
- Origin
- Manufactured in Montreal but the specific down certification is not disclosed.
- Practical use
- Best for winter only and requires specific care to maintain loft.
- Washing
- Wash 2-3 times a year on cold (max 30°C) in a front-loader, no softener, double rinse.
- Drying
- Dry on low heat for 2-3 hours, pausing to break clumps, using tennis balls, then air-fluff 10-15 min.
- Storage
- Store in a breathable cotton bag only when fully dry.
- Provenance
- Montreal-made with a generic Responsible Down certification.
- Box stitching
- Box stitch locks fill in place and lets heat escape; winter-only per reviews.
- Down quality
- At 600 FP, duck down insulates like goose, with breathability and ethical sourcing, in the 'very good' tier.

Parfaite pour les frileux
Couette légère tout en fournissant une très bonne chaleur. Ça fait quelques semaines que je l’ai et le duvet reste en place dans ses compartiments.
Really great!
It's really fluffy and comfortable! Quality seems very good, glad I bought this.
Très (trop?) chaude et un peu rigide
OK pour l’hiver J’en ai commandé une autre ( 4 saisons) pour le reste de l’année
So Good
Just, so, so good.
Boreal Prestige duvet
The duvet was exactly as advertised and so what we expected. It is warm and cozy . It was delivered faster than we expected. We are very happy with it.
Légère
Oui je le recommanderais Mais il faut être bien convaincu quand on voit le prix
Good product but disappointing at the same time
I really like the duvet, light weight but at the same time very warm. Trust me when I say warm because I’m always cold even during summer. There is one reason I won’t give more than 3 stars. When i saw the product on the Simon’s website on the specification I red “proudly made in Canada” …. That’s why I bought it. When I got it I check the tag that says “assembled in Canada”… I assume the material is from china. Disappointing for that.
