Does anyone use compression arm sleeves?

No I haven’t used them and it is not really warm here yet.

But I think if I went back to saerious weight training I would try compression sleeves.
Your reasoning about warmth and such makes sense though I donmt know why you are wearing compression clothing to begin with.

I didn’t think anyone was ever going to answer this!!! I wear a compression short sleeve because it keeps me warm and I like the feeling in general. I wear compression tights in cold weather. Seems to keep muscles warm and I have less fatigue or soreness after a long run when I wear them. Since I already have a short sleeve shirt, I don’t feel like spending the exorbitant amount of money for a long sleeve so I thought maybe just the sleeves would be a good compromise !
