The Moorea Duo 250 4-season duvet pack is the most versatile and most complete pack in the Moorea goose down range. It consists of a Moorea summer duvet and a Moorea Plus all-season duvet. Both duvets are filled with natural white French goose down (90% down and 10% feathers). The different fill weights of these two duvets — known as fill ratings — allow for truly versatile comfort. The Moorea Été duvet is lightweight with a fill weight of 100g/m², while the Moorea Plus is an all-season duvet with a fill weight of 150g/m². Both duvets feature a premium white cotton sateen cover and beautiful grey sateen finishes. Separately, these duvets are perfect for the mid-season and even summer, and by pairing them together using their clever press-stud system, you get a much warmer duvet, ideal for winter when your bedroom temperature is quite low. Available sizes range from single to the largest double.
