indeed. I have one pair of arm warmers, Assos no less, that I hate. They're snug and warm and well made and all that, but they have a very firm gripper and I end up with a gripper tattoo across my bicep and sore skin near my armpits. I have one pair of knee warmers and one pair of leg warmers that I like and use a lot. Sportful is their unelegant name. The gripper is fine on me, the material is very thin, only drawback is the full-length ones have gotten a bit sloppy and loose, and they were always a bit short. Very handy for days when it'll heat up later, common weather here. The arm warmers I only wear when I'm pinched for storage space.

Maybe it's just a size thing.
