Is this sweater true to size?

It is a regular fit, so most men take their usual size. If you want a looser layer over a shirt, size up.

Yes, it is knitted from cashmere. That makes it soft and light, but it needs hand washing or a wool cycle and flat drying.

How does it compare with a wool rollneck?

Cashmere is softer and lighter than wool, but wool resists pilling better and costs less to replace. Choose this for feel and drape, wool for durability.

Can I wear it under a blazer?

Yes. The fine gauge and regular fit keep bulk down, and the rollneck works under a soft-shouldered jacket.

How should I wash it?

Hand wash in cool water with a wool detergent, or use a wool cycle, then dry flat. Never tumble dry or hang it wet.

Cashmere pills with friction, especially under the arms and where a bag rubs. A fabric comb removes the pills and the pilling usually settles after a few washes.
