I started a new character a while ago. This time it's a mage.
On my other character, where I already played >50h I found about 3 simple leather gloves (which seem to be the only and only gloves other than armor type gloves in the entire game).
On my mage character (played about 20h already) I haven't yet found any gloves, and I even checked numerous shops for clothing and other goods numerous times to get them.

It's RIDICULIOUS!

We live in Skyrim, a land of cold and snow, but nobody is interested in gloves?
Every shop, which sells clothes should also sell gloves.



Anyways, how can I add them per console?
Item ID?
I know that Belethor in Whiterun is wearing gloves. But since my mage is a good character it would be a bit over the top to kill him just for that.

Have you tried the clothes shop in Solitude? They tend to have everything.

Fort Graymoor? That place has [censored] loads of random clothes including gloves.

And FYI, it's never wrong to kill Belethor.

I got mine during the mages guild quest line.

I haven't seen any others myself.
