Just give the guy some armour using whatever method you prefer-or enjoy the view. That seems to be an issue with the original mod.

There's also a chance you'll find a random naked guy in the great hall at Windhelm. I am aware there are some minor clipping issues when moving, and some of the light armours are problematic when guards are at larger body sizes - even deleting vertices there's only so much I can do on those ones. NordwarUA for the original mod and for permission to convert I find it's wonderful for immersion, but unfortunately wasn't compatible with SAM, so. What the original mod does is give all the guards from the various holds of Skyrim unique armour sets, each reflecting the culture and history of the hold. Unlike a lot of other mods, this isn't designed for the player, although you can certainly get and wear the various armours.

This replacer assumes you're using the full Guards Armour Replacer mod, which requires all DLC and USLEEP. You WILL need to install the original mod for this to work - then install my mesh refits over the top - all I've done is refit the meshes for SAM and package them up. This is a Legacy Edition SAM refit of NordwarUA's Guards Armor Replacer.
