These gloves can work for either a girl or a boy! Thank goodness, I'm a very petite girl w/ small hands (I wear kids XL or adult XS football Underarmour gloves, just for reference) and the S/M ones fit very well! The Sumo print is adorable.
I got a pair for my BF in the M/L, after reading that these run big. I don't think they do at all; in fact, there's barely any difference between the S/M and M/L. This worried me because his hands are super skinny but his fingers are at least 1 inch longer than mine. However, they fit him perfectly.
Oh yeah-the gloves are very soft, thin enough to fit inside my leather winter gloves, and that touch-screen thingy is on both the thumb and forefinger! It totally works too! Some people complained in other reviews that they're too thin; I disagree. Thicker does not necessarily equal warmer. And sure, a little tackiness would be nice, but then that would make it difficult to slip in/out of your real gloves. So I think these were designed perfectly for the intended purpose.
