This is my first pair of sun sleeves, and so far I like them. I usually wear a women's small in OR tops, purchased the smaller size in these, and I haven't had a problem with slippage. The sun sleeves come up a little higher on my long arms than I'd expected, which means I won't have a gap with short sleeves. I appreciate the hand coverage, but I don't expect the palms to hold up to much scrambling. The fabric does feel like it will hold up to abrasion from brush and rock better than my Echo hoodies.
