Classic, cable knit 100% cashmere luxury sweater for pets.  The quality is amazing, read below to see why it's worth investment! Why cashmere?  Softness  Cashmere is from the soft fleecy underlayer of a cashmere goat and these fibers are extremely fine which is why cashmere is so soft.  When properly cared for, cashmere gets even softer with age! Insulation Cashmere goats live in a harsh climate and makes their wool 8x more insulating than regular sheep's wool. Lightweight: Cashmere is not a bulky fabric and still provides superior insulation / warmth. Moisture Wicking: Cashmere has a high moisture content and as humidity changes it is able to adapt, making it comfortable even in warm climates.  The exterior of cashmere fibers are water repellent while the interior attracts moisture, such as sweat, away from the body.   Breathable Unlike synthetic fibers which trap heat in, cashmere allows the body to breathe which helps regulate temperature. Comfortable Cashmere is not scratchy like other wools and feels soft against the body.  It also has natural stretch and is easy to move around while wearing.  Hypoallergenic Cashmere has hypoallergenic properties making it a perfect choice for the fur baby with allergies.
