Insulation

Silk duvet inners provide excellent insulation while remaining lightweight. We offer two different weights of silk duvet inners, The Summer Silk Duvet Inner which is ideal for warm climates like South Africa but thick enough to keep you warm during winter, and the Spring Silk Duvet inner which is a slightly thicker silk (Tog rating of 6.4 – see below to understand tog ratings) for those who feel the cold more. Duck down also offers excellent insulation, but hollow fiber is not as effective.

Breathability

Silk is highly breathable, allowing for comfortable temperature regulation. Duck down is also breathable but less so than silk, while hollow fiber may trap more heat resulting in a potentially sweaty experience during the night.

Hypoallergenic

Silk duvet inners are hypoallergenic and suitable for people with allergies. Duck down can trigger allergies in some individuals, while hollow fiber is generally hypoallergenic.

Lightweight

Both duck down and silk duvet inners are lightweight with silk being lighter overall, making them easy to handle and comfortable to sleep under. Hollow fiber duvets are also lightweight. Silk Duvet inners may seem flat but have the lightweight properties and insulation properties provided by nature herself to keep you warm.

Temperature Regulation

Silk duvets excel at temperature regulation, helping to keep you cool in hot weather and warm in cold weather. Duck down provides good temperature regulation, while hollow fiber’s performance depends on the quality. We offer two different weights of silk duvet inners, The Summer Silk Duvet Inner which is ideal for warm climates in Africa but thick enough to keep you warm during wineter, and the Spring Silk Duvet inner which is a slightly thicker silk for those who feel the cold more.

Durability

Silk duvet inners are relatively durable but may require more care (5 year replumping is recommended – done free of charge at our factory). Duck down duvets are also durable when properly maintained. Hollow fiber duvets may have a shorter lifespan.

Moisture Wicking

Silk has natural moisture-wicking properties, helping to keep you dry and comfortable. A moisture-wicking fabric has two jobs: one is quickly moving (or wicking) sweat to the fabric’s outer surface, and the other is drying rapidly so that your sweat doesn’t saturate the fabric. Duck down does not wick moisture, and hollow fiber may retain moisture to some extent.

Ease of Maintenance

Silk and duck down duvet inners require more care and may need professional cleaning. Silk has natural dirt repelling properties and does not need regular cleaning. If you need to wash the silk duvet, we recommend dry cleaning from time to time. clean in cold water with Hollow fiber duvets are easier to clean and maintain at home.

Luxurious Feel

Both silk and duck down duvet inners offer a luxurious and soft feel with silk feeling a lot lighter and “cloud like”. Hollow fiber duvets can vary in their texture and feel depending on the quality.

Ultimately, the choice between silk duvet inner, duck down, or hollow fiber duvet inners depends on your personal preferences, budget, and specific sleep needs. Silk duvet inners are prized for their luxurious feel and excellent temperature regulation, making them a popular choice for those who can afford them and prioritize these qualities.

 

 

What is inside your duvet?

SILK BATTING

Silk duvet inners are made using pure 100% silk batting in different togs to create the ideal weight and warmth for the season or climate.

Silk batting is identifiable by the sheen on the silk.

In South Africa in particular, we use 3.2 tog for summer duvets and 6.4 tog for winter duvets.

Custom tog silk duvets can be ordered and manufactured by special request. The lowest tog is 2 tog which is required for full coverage.

POLYESTER/HOLLOW FIBRE FILLING

Polysester is the material used to create hollow fibre duvet filling. It essenially tries to immitate silk but apart from looking similar to silk in some respects, it does not have the same temperature regulation capabilities or the longevity.

Hollow fibre is much cheaper than silk or any of the feather fillings. 

Hollow fibre is light, is springy to the touch and retains it’s puffiness fairly well. It is not possible to reinvigorate hollow fibre like Silk duvet inners. 

DUCK DOWN/FEATHER FILLING

Feather filling, including various grades of duck down are the most common and popular fillings found as duvet fillings around the world.

Goose and duck down have very good thermal properties, helping to regulate temperature and as with Silk, the tog of the duvet determines what climate it is ideal for.

The tog of top quality duck/goose down duvet inners require less feather material to achieve the same tog rating. 

What is a tog rating

The tog rating is a measure of the warmth of a duvet. It indicates the ability of the duvet to trap and retain heat and and when combined with the ability of the filling materials heat regulation properties, means, the higher the tog rating, the warmer the duvet.

The tog rating system provides a standardized way to communicate the thermal insulation of a duvet. Here’s a general guide to tog ratings and their corresponding warmth levels:

2.0 to 6.4 Tog

These are lightweight duvets suitable for warmer weather or for people who prefer a cooler sleep environment. Our Silk Duvets are made in 2 different togs, 3.2 tog for summer and 6.4 tog for spring/winter.

At SILK.co.za we manufacture to order and are able to customize any duvet to the tog rating you require.

Silk Duvet Inner 3.2 Tog

Silk Duvet Inner 6.4 Tog

6.4 to 10.5 Tog

These are medium-weight duvets, suitable for cooler nights or for use in bedrooms with average temperatures.

12 to 13.5 Tog

These are heavyweight duvets designed for colder seasons or for individuals who tend to get cold during the night.

Over 13.5 Tog

These are extremely warm duvets, ideal for very cold climates or for individuals who are particularly sensitive to cold.

It’s important to note that personal preferences and individual factors, such as room temperature and personal body warmth, also play a role in choosing the right tog rating. Some people may find a lower tog rating sufficient even in colder weather if they tend to sleep warmly, while others may need a higher tog rating for extra insulation.

It’s a good idea to consider the tog rating in conjunction with the material and construction of the duvet to ensure the desired level of comfort. Additionally, some duvets come with options for different tog ratings on each side, allowing users to adapt to changing seasons or personal preferences.

In the case of silk tog ratings, it is possible to tie tie two of the summer duvets (3.2 tog rating) together to create a Spring Dub=vet. (6.4 tog rating)
