Expert Guide to Choosing the Best Knitwear for Arctic Winters

Like an emotional support sweater, a good piece of knitwear can make leaving the house in arctic temperatures feel not only bearable, but comfortable and chic. However, not all knitwear is created the same. Understanding the differences between fabrics is crucial for making a smart purchase.

Before purchasing a knit, it’s helpful to know the difference between the different wools and blends, said Kim Appelt, celebrity fashion stylist and author of “Style for Everybody: A Guide to Curating Your Essential Wardrobe.” Polyester blends might feel impossibly soft initially but can degrade quickly, while natural fibers like cotton and cashmere offer superior thermoregulation, durability, and a luxurious feel.

Proper care is essential for maintaining knitwear. Never hang knits, advised Melissa Rivers, fashion expert and former co-host of E’s “Fashion Police.” If you absolutely have to, support them fully so they don’t stretch out. Otherwise, folding is always the safest bet.

Top Fabrics for Lasting Warmth

We consulted fabric experts to identify the best materials for knitwear that lasts and keeps you warm season after season.

Wool: Appelt noted that wool is stronger and holds its shape better, making it great for structure and warmth. It provides enhanced moisture-wicking properties, ideal as a base layer for outdoor activities.
Cashmere: Tara West, a fashion expert, described cashmere as timeless, ultra-soft, and warm without bulk. She recommended two-ply cashmere for shape retention and folding instead of hanging. Rivers added that cashmere is lightweight, long-lasting, and feels like a warm hug. However, Appelt cautioned that it tends to pill, suggesting blends for better durability.
Alpaca: West highlighted alpaca as warmer than traditional wool yet lightweight, hypoallergenic, and luxurious. Blends shed less and retain structure better for everyday wear.
Cotton-Cashmere Blends: West called this blend the ultimate closet MVP, offering breathability and softness with less delicacy, perfect for year-round use.
