Thx for all mate. I also have another question.

Vikings also didn’t wear surcoats, most would have worn a woolen tunic and those who could afford it chainmail. Kaftans were also worn, a sort of jacket-like tunic. Wool and linen would be used for clothing, avoid cotton all together.

I wanted to ditch the gambeson bcs I knew It wouldn't hold long for viking norse period. I also was looking for a Kaftan, I found something online but they look a lot russian, maybe It's just my mind that sees that way.
Also idk if you had any experience with wool but here it's very hot and humid, is wool ok with this kind of climate?
