I bought these because I'm wearing a tennis elbow brace on my right arm and my forearm was getting cold, with my sleeve pushed up. What I wanted were very basic, lightweight knit arm warmers, and that is what I received. The two are ambi-fitting, which is great for my particular use (when one wears out/unravels, I'll use the other one). For the price, it's about what I expected, inclusive of the thumb holes in both arm warmers unraveling a little, even in the packaging. I snipped off the thread and it doesn't seem to be any worse for the wear.

A word of caution: Velcro will WRECK these. So keep that in mind if you're wearing them around coats, bags, etc.
