Warm, all-season or light duvet?
Warmth rating, fill weight and fill power
All our duvets feature a filling of upcycled natural feathers and down, renowned for its lightness and thermoregulation properties.
Refer to the TOG rating, which measures the warmth of the duvet:
- Light duvet (TOG < 7.5): Ideal for summer or for those who always feel warm at night. Highly breathable and perfect in a heated bedroom, its fill weight is generally between 80 and 180 g/m².
- All-season duvet (TOG from 7.5 to 12): Perfect for the transitional seasons (spring and autumn) or a bedroom between 18 and 20°C. It is often the right year-round compromise in a well-insulated home. Its fill weight is generally between 180 and 220 g/m².
- Warm duvet (TOG> 12): For winter or cool, poorly heated bedrooms. It retains heat very well, perfect for those who feel the cold. Its fill weight is generally between 250 and 360 g/m².
Fill power, "filling power", measures the ability of down to regain volume after compression. The higher the fill power, the lighter, more insulating and therefore higher quality the down. It is expressed in cuin (cubic inches
per ounce).
- 300–400 cuin: standard quality
- 500–700 cuin: premium quality
- > 800 cuin: exceptional down
At Pyrenex, the fill power of our duvets ranges from 480 to 850 cuin, offering premium to exceptional comfort depending on the model.
Which shell to choose?
Thread count
The thread count per square centimetre indicates how many threads are woven into one square centimetre of fabric. The higher this number, the tighter, more durable and softer against the skin the fabric is. The minimum for a shell containing down is 78 threads/cm².
Weave
For better breathability, Pyrenex favours shells in pure cotton. Our products range from plain weave and twill, known for their durability, to satin and jacquard, which are more elegant and silky to the touch.
Finish
The finishing details play an important role in durability, aesthetics and comfort.
- Satin stitch: a decorative stitch used to add relief to embroideries.
- Double stitching: a decorative stitch along an edge that creates two parallel threads.
- Piping: in satin or cotton, with or without a cord (a cotton thread inside the piping that forms a small raised bead), it accentuates the prints or cut-outs on pillowcases and facings.
- French seam: an open seam in which both seam allowances are folded inward.
- Box wall: a strip of fabric that connects the upper part of the duvet to the lower part and visually creates volume.
- Inner baffle: a strip of fabric that connects one chamber to another, acting as a partition inside the duvet to ensure a more even distribution of the down inside.
