Which is warmer — cashmere or alpaca?

The short answer is: Alpaca is warmer.¹

While both fibers are excellent insulators, alpaca wool fibers have a hollow core that traps heat more effectively than cashmere.² However, cashmere is often prized more for its “buttery” softness and lighter weight.³

Here is a quick breakdown of how they compare to help you decide which is right for you.

	Cashmere	Alpaca
Primary Benefit	Primary Benefit Extreme Softness	Primary Benefit Warmth & Durability
Warmth Level	Warmth Level Very Warm (3x warmer than wool)	Warmth Level Warmest (7x warmer than wool)
Durability	Durability Delicate (prone to pilling)	Durability High (resistant to pilling)

Top Picks for Cashmere (For Softness)

If you want that classic, cloud-like feel against your skin, cashmere is still the gold standard.⁴

Best Value Option: Quince Mongolian Cashmere Crew

This sweater has disrupted the market by offering 100% Grade-A cashmere for around $50.5 It is lightweight, perfect for layering, and comes in over a dozen colors. It isn’t as thick as luxury brands, but for the price, the quality is unbeatable.

Best Mid-Range Option: Naadam The Original Cashmere Sweater

Naadam sources directly from herders in Mongolia.6 Their “Original” sweater is slightly softer and denser than the Quince version. It is famous for being machine washable (though hand-washing is still safer) and often features vibrant, unique colors you can’t find elsewhere.

Top Picks for Alpaca (For Warmth & Durability)

If you want a sweater that can survive a hiking trip and keep you warm in freezing weather, go with alpaca.

Best Everyday Hoodie: Paka The Hoodie

Paka uses Royal Alpaca, which is the finest and softest grade of fiber, so it doesn’t feel itchy like old-school wool.7 This hoodie is durable enough for outdoor adventures but stylish enough for the city. It regulates temperature incredibly well, so you won’t overheat when you step inside.8

Best Technical Layer: Appalachian Gear Co All-Paca Fleece Hoodie

This is 100% alpaca fiber engineered into a lightweight fleece.9 It is incredibly warm for its weight, odor-resistant (you can wear it for days without washing), and tough. It has a more “rugged” look than the Paka hoodie and is ideal for hiking, camping, or travel.

If you let me know if you are shopping for lounging, work, or outdoor activities, I can recommend a specific style (like a thick cable knit or a lightweight cardigan) that fits your needs.
