Norsemen in sagas

Is there anything about the physical appearance of the Norsemen in Icelandic sagas?? I'm also interested in the description of their way of living et cetera. Thanks in advance.

The sagas often give detailed descriptions of individuals, but rarely of whole groups. For a general description of the Norsemen try the 10th century Arab writer Ahmad ibn Fadlan's account of his encounter with them on the river Volga, where he not only describes physical appearance and dress but also social and religious aspects. Here is an excerpt:

"I have seen the Rus as they came on their merchant journeys and encamped by the Itil. I have never seen more perfect physical specimens, tall as date palms, blond and ruddy; they wear neither tunics nor caftans, but the men wear a garment which covers one side of the body and leaves a hand free. Each man has an axe, a sword, and a knife, and keeps each by him at all times. The swords are broad and grooved, of Frankish sort. Each woman wears on either breast a box of iron, silver, copper, or gold; the value of the box indicates the wealth of the husband. Each box has a ring from which depends a knife. The women wear neck-rings of gold and silver. Their most prized ornaments are green glass beads. They string them as necklaces for their women."
