Is a wool-cashmere blend warm enough for winter?

Yes for most climates when layered. The wool gives warmth and the cashmere adds softness, but it is a mid-weight knit rather than a heavy outdoor sweater, so it works best under a coat in cold weather.

How should I wash it?

Treat it as a delicate wool garment: hand wash in cool water with a wool detergent or use a wool cycle, then dry flat. Avoid a hot dryer, which will shrink and felt the knit.

Cashmere-blend knits can pill where they rub, such as under bag straps and at the cuffs. Removing pills with a fabric comb or shaver keeps it looking neat.

How does the fit run?

It is described as a relaxed, straight fit, so it sits away from the body rather than close. If you want a trimmer look, consider going down a size.

What makes it different from a plain lambswool sweater?

The cashmere content gives it a softer hand and lighter feel than standard lambswool, while the wool keeps it more structured and durable than pure cashmere.
