General Info on Wool Duvets


Wool is often called the miracle fibre – a wonderful insulator, excellent at moisture control, naturally flame resistant, highly resilient and many other good things.

For thousands of years man has had a beneficial relationship with this unique fibre, but only in more recent times has science discovered why wool is such a miracle fibre and why it is the perfect choice for bedding products. The secret is in each wool fibre.

Moisture Control

The core of each wool fibre is very absorbent – up to 30% of its weight in moisture. By comparison cotton absorbs 8% and most synthetics as low as 2%.  In fact wool is the most hydrophilic (able to absorb moisture) of all natural fibres.  The wool fibre is unique in that it then releases this moisture slowly through evaporation helping the sleeper stay warmer in winter and cooler in summer, and eliminating dampness in the bedding.

Natural Temperature Control

As wool fibres release absorbed moisture, heat is given off.  In fact, a single gram of wool gives off 27 calories of heat when it goes from wet to dry.

Naturally Non Allergenic

The keratin in wool is the same protein as in nails and hair.  Dust mites – a leading cause of allergies – prefer a damp, not dry location, and the scales which cover each wool fibre help further create an inhospitable environment.

How to choose a wool duvet

The wool fill should be hi bulk (trapping lots of air for insulation), resilient and light in weight. A flat, heavy wool duvet indicates poor quality wool that will not insulate well.

The cover should be soft, breathable and allow the wool fill to contour the sleeper’s position. If the cover is stiff, rustles or is hard to breathe through, it means the cover is probably down proof cotton which eliminates wool’s moisture controlling benefits.
