Why We Love Merino Wool Sweaters

Merino wool comes from Merino sheep, and the fibre itself is what sets it apart from conventional wool. It's finer, smoother, and naturally temperature-regulating. It keeps you warm when it's cold and breathes when things heat up. 

Wool can absorb up to 30% of its weight in moisture before it even feels damp, too. It’s been the fibre of choice on the Aran Islands for centuries. Fishermen and farmers along the harsh Atlantic coast relied on it back in the day, and it’s still a go-to today.

But wait - are merino wool sweaters itchy? Not at all! That scratchy reputation belongs to coarser wools. Merino is in a totally different league. Here are some of the many reasons you need a merino wool sweater in your wardrobe:

• Naturally elastic: Wool fibres stretch up to 70% without losing shape so the sweater moves with you
• Odour resistant: The fibre doesn't trap bacteria the way synthetics do, so you don’t have to wash it after every wear.
• All-season: Insulating air pockets work in both directions, keeping cold out and letting excess heat escape
• Built to last: A well-made wool sweater outlives most things in your wardrobe by years

Heavier wool knits do take longer to dry, and storage matters. Fold them flat, never hang, and keep moths at bay with lavender or cedar. Follow those tips and there honestly aren’t any “drawbacks” to wool sweaters! So, how does the other half of our wool vs cashmere sweater comparison stack up?

Why We Love Cashmere Sweaters

Cashmere comes from the fine undercoat of cashmere goats. The fibres are thinner and softer than standard wool. That’s where cashmere’s unmistakable feel comes from - that immediate “this is different” moment when you pull one on.

Our wool-cashmere blends pair that softness with the structure and durability of Aran wool, so you get the luxury without sacrificing longevity. It’s the best of both worlds. Here’s why cashmere earns wardrobe space:

• Featherweight warmth: Cashmere fibres insulate without the bulk. Blends feel way lighter on the body than a 100% wool sweater.
• Refined drape: Sits closer, falls cleaner, looks polished without trying
• Skin-kind: Even people sensitive to traditional wool rarely have issues with cashmere-blend knits
• Gift-worthy: There's a reason cashmere is the go-to for meaningful gifts!

A few things to keep in mind, though. Cashmere fibres are finer, so they can pill over time with friction. Gentle hand washing and flat drying go a long way in preventing or at least minimising that.

Cashmere and cashmere-blend pieces do sit at a higher price point because the fibre is rarer to produce. However, the jump from pure wool is smaller than you'd expect with our blends at Aran Sweater Market.

Cashmere vs Wool Sweater: Side-by-Side Comparison

Both fibres have genuine strengths. The wool vs cashmere sweater debate usually comes down to what you're prioritising on a given day. Honestly, most people end up wanting both once they understand the differences.

Comfort and Softness

Cashmere wins on first touch with fibres thinner than human hair. You feel that against your skin right away. Our cashmere cardigan collection is where that softness really shows up. The blend drapes beautifully without losing the cable-knit texture that makes an Aran sweater unmistakable. 

On the other hand, merino wool is softer than most people expect. If your only experience with wool is a scratchy jumper from childhood, a merino wool sweater for women or men's merino wool sweater will change that assumption fast.

Warmth and Breathability

Wool is the warmer fabric for sure. Dense Aran knits trap more air, and that’s what actually insulates you. This is the material to go with for raw warmth in a proper Irish winter, or anywhere the wind cuts through. 

In contrast, cashmere blends are warm - but more lightweight. Think of it this way: wool is the coat you grab when it's genuinely cold. A cashmere blend is the one you layer under a jacket on a crisp evening without feeling bundled up. Both are warm, but to different extents.

Durability and Longevity

Wool takes this one as well since the fibres can bend thousands of times without breaking, and a traditional Aran sweater is built to be passed down - some containing upwards of 100,000 hand-constructed stitches! We've had customers tell us their mothers wore the same sweater for 20 years. 

Cashmere is more delicate by nature. The finer fibres are more prone to pilling, especially at friction points like the underarms and sides. Our blends help offset that, though. The 95% wool structure does the heavy lifting while the cashmere adds the luxurious feel and softness.

Care Requirements

Neither fibre belongs in a washing machine, so expect to commit more time to care for whether you go with a cashmere vs wool sweater. Hand wash with a wool-safe detergent, soak for 5-10 minutes, roll in a towel to press out water, and dry flat. That goes for both. 

The difference is forgiveness. Wool bounces back from minor mishaps more readily. Cashmere has a little less margin for error. Store both folded (never on a hanger as gravity stretches the shoulders) in a breathable space with some lavender or cedar nearby. 

Either way, a wool vs cashmere sweater treated properly will last you years either way, so it’s worth giving your garment the TLC it deserves!

The Cost Side of Things

Pure wool Aran sweaters start at $64.95 for traditional styles. Merino sits in the $89-$139 range. Our wool-cashmere blends come in between $129 and $169, which you know is actually a fraction of what most brands charge if you've taken a look at 100% cashmere sweaters elsewhere.

The reason is simple: blending cashmere with wool gives you the feel without the markup that comes with sourcing enough raw cashmere for a full garment. You still get the luxury, though.

Final Words on the Wool vs Cashmere Sweater Comparison

The honest answer to the wool vs cashmere sweater question is you probably want a chunky Aran wool knit for the days when warmth and durability matter most, and a cashmere blend for the moments when softness and drape take priority. 

They’re different tools for different days, but both are made to last. Think about how you dress if you're choosing just one to start. 

• Merino wool works great for layering over flannels and spending time outdoors. 
• A cashmere-wool blend is lighter and looks more sophisticated with jeans or over a dress.
