This post I wrote a year ago may be helpful.

In the mid-seventh century, the standard weapons would have been shield and spear. Armor is rare in the archaeology, and was probably rare on the field as it represents an enormous investment in material wealth (iron, fuel, and skilled labor) to produce. Swords, which had been much less common than spears in the century before, were probably still less common, though the Staffordshire Hoard contained pices of about 80 different swords so they weren't rare. Warriors might have carried large knives called seaxes, though they could also have been hunting or carving knives, rather than weapons -- we're not quite sure.

Shields, by the seventh century, had grown wide, about 80cm. They were round, and their boards were probably slightly convex. The boards were willow, poplar, or linden (usually), and were faced on the front and usually the back with hide -- probably rawhide, but maybe tanned leather). They were gripped by a handle in their center, over which was riveted a 'boss', an iron cone. Seventh-century shield bosses in england were usually shaped like a suagr loaf (this image is a reproduction).

Spears were thin, graceful weapons, with blades averaging about 300-400mm long. The spearheads were iron, sometimes with steel edges welded on. Leaf-shaped blades like these ones were most popular. The shafts were made from resilient wood like ash, or naturally straight saplings like hazel. Spears were about 2m long, weighed less than 1kg, and were used in one hand (the other gripping the shield). They could have been thrown or used to stab, and many were probably used for both purposes.

Swords were heavy weapons, designed to strike devastating skull-splitting blows rather than for quick fencing (if you wanted to fence, you used a spear). They were typically just shy of a meter long, and had short grips with room for only one hand. Their blades were almost always pattern welded, a decorative techniqur that mixes multiple alloys of different colored iron into intricate patterns. This didn't make the sword strong, but it did show off the maker's skill -- proof that he knew what he was doing, and by extension that the sword's quality could be counted upon. Here's a reproduction of a pattern welded sword.

Body armor would have been mail, but we have only a single surviving mail coat from England, buried in the king's ship burial at Sutton Hoo. Penda probably had mail, as did his chief men -- but there's little reason to believe hiw whole army would have been so fortunate. Bear in mind that a spearhead weighs 200g, and a sword aboud 1kg. A mail coat can weigh 10-13kg easily, making it equivalent (setting aside thr question of metal lost to ha,merscale for the moment) to 50 spearheads or a dozen swords. That's a lot of material, and a lot of fuel to form it into the tens of thousands of rings that made up a mail coat. The fact that we've only found one from the entire early medieval period in England accords with their expense and rarity. A typical warrior's armor was his or her shield.

For helmets, we have more evidence. The most famous helmet of the seventh century was buried at Sutton Hoo, and helmets of a similar artistic style are found in graves in Sweden later in the seventh century. We also have the Pioneer / Wollaston helmet, from a seventh century grave. It's less decorated than the Sutton Hoo helmet and probably better represents the 'normal' helmets of the period (though a helmet, like a sword, was probably not a 'normal' piece of kit for the ordinary soldier -- this is what the rich and/or famous warriors wore. This helmet's style is echoed in the eighth-century Coppergate helmet, further suggesting the popularity of the design. Finally, there's a helmet made from an iron frame with cattle horn panels, buried with a man at Benty Grange. This is my favorite from the period, but we have no way of saying whether its design (unique in the archaeological record) was unique or common in its time.

There is no evidence that leather armor of any kind was worn in this period. There might be evidence for use of cloth armor in the Sutton Hoo ship burial, though this is a rather dubious interpretation in my eyes.

So your typical warrior would have been unarmored, and would have carried a single handed spear, centre-grip shield, and perhaps a long knife. The person who commanded him or her would have had a sword, and might have also had a helmet like the Pioneer helmet linked above. The king, and perhaps a few of his best warriors, may have had more magnificent helmets like that in Sutton Hoo or those in Valsgarde, Sweden, and some of these may also have worn mail.
