GSD is the culmination of Dumas Paris' research in terms of improving comfort and optimizing product safety. This patented concept of the double shell allows to stop and to block the contamination resulting from the migration of mites and allergens.

The outer shell is an untreated textile which guarantees the comfort of a hypoallergenic contact. The inner liner receives a specific treatment and serves as a barrier to the harmful elements. This treatment contains a biocidal product SANITIZED® PL21-60 in compliance with EU requirements No. 528 / 2012. The two envelopes work in synergy to ensure maximum comfort and safety for humans and their environment.

The GSD label on the packaging indicates that your product benefits from this technology.

In the tradition of the Great Houses, Dumas Paris offers you the possibility of personalising your duvet with you initials

all seasons Microfiber duvet Alliance Alliance

Two duvets to form one: a summer duvet and a mid-season duvet interlinked by links to form the winter duvet. One ensures comfort and lightness for the summer nights and the other gives you an enveloping welcome for the mid-season. These two quilts joined by cotton ties, bring the ideal heat level for the winter season. This synthetic duvet can adapt to all seasons and all regions of the world.

Composition The summer duvet and the inter-season duvet are filled in 100% microfiber. The outer shell is a down-proof satined cotton, 140 threads/cm². The summer duvet has a grammage of 200 g/m², it will be perfect for the warm seasons. Te inter-season duvet has a weight of 300g/m² and will therefore be neither too hot nor too cold at the exit and at the beginning of winter. Together, the duvets create a warm cocoon for the winter. These quilts have a satin stitch finish, the strongest stitching possible. An anti-mite and anti-bacterial treated non-woven lining, exclusive to GSD®, can be applied to the duvet.
Packaging The duvet is delivered in a protective Dumas Paris canvas bag which you can use to store the duvet during the hottest months of the year. You can also use the bag for leisure and travel.
