Which wool is really the warmest?

Keeping warm

When it comes to the warmest fabrics for cold weather, wool always ranks number one! While we’re certainly firm believers that wool isn’t just for winter, there are many reasons why this fantastic fibre is an excellent insulator against the harshest conditions. We’ll let Modern Ratio explain more:

“Make sure you stock up on wool sweaters for the winter — this fabric is the warmest you can find. As you probably know, wool comes from sheared sheep (and sometimes other animals). It has natural insulating and moisture-wicking properties that keep you warm in wintry weather. If you’re worried about wool fabric making you itch, try the merino variety instead. It’s much softer and more comfortable than regular wool.”

There are so many different types of wool to choose from – including in our collection of all-natural homewares and accessories – yet not all wool fibres were created equal. Some wool types are warmer than others.

Here we reveal the warmest wool the natural world has to offer, meaning you can make the transition to the cooler months with ease and even save on those energy bills!

Merino wool

With durability, water resistance and excellent insulation just some of the benefits that go hand-in-hand with using a Merino wool blanket, it should come as no surprise that it’s ultra-warm too.

Merino wool may be thinner than regular wool, but the structure of its fibres makes it a cut above the rest. The natural crimp of Merino fibres traps and retains heat, while its moisture-wicking qualities will keep you warm and dry even when it’s wet.

Cashmere

Like Merino wool, cashmere fibres are finer than regular wool, and do a fantastic job trapping and retaining heat as a result. They do all this without the extra weight or bulk, making it a joy to snuggle up beneath during the autumn and winter months.

When compared with Merino wool, however, the cashmere in a traditional cashmere throw blanket can be up to eight times warmer, with its higher loft also making it super soft to the touch.

Lambswool

Don’t underestimate the warmth of lambswool. Made from the fleeces of young sheep, and typically taken during a lamb’s very first shearing, the lambswool you can find in our wool blankets offers a smoothness and softness that’s made for use during the cooler seasons.

Alpaca wool

Alpaca wool is another superstar; while a little stiffer than Merino wool, its fine, lightweight and soft fibres offer a silky finish that’s surprisingly warming. In fact, the alpaca wool you can find in an alpaca blanket is both lighter and softer than sheep’s wool. Its hypoallergenic qualities also mean a soothing softness that even those with the most sensitive of skin can relish.

Mohair

Sourced from the Angora goat, the mohair in a mohair throw offers a thickness that screams warmth. It is renowned for its smoothness, durability and resilience, whilst its vibrancy and natural lustre ensure a beautiful addition that’ll keep your home stylish and warm from season to season.

Vicuña

As well as taking the crown for the most luxurious natural fibre on the planet, vicuña is one of the warmest. Its fibres are finer than cashmere, offering an unrivalled softness and warmth that was once reserved for royalty. It is however also the rarest and most expensive type of wool in the world!
