I wonder what the difference is between those and these, besides $38. The "long underwear" wears like leggings or tights and they're definitely lighter weight than SW "midweight" tops. (That's actually my only complaint about them, the fabric is so thin that I don't dare wear them on the bike.) I looooooove mine.


ETA: hmmmmmmmmm, REI fall sale, I might need another pair of those....
