Let me know how you like the Thermosilk. I got mine at LL Bean, petite sizing. The bottoms are fine, but the top is cut a bit too short. I'm looking to invest in another pair for home sleeping purposes, not just traveling.

Joy, will look for sure. My problem is I'm really picky and don't want to just go, oh, something from Ireland, that I wouldn't use. I did plan to look at sweaters but bulky pullovers can overwhelm me so will have to see.

Shiny, I ordered this very lightweight Thermasilk after trying on in store but they did not have the color, it's whisper-thin, in part for my real life at home, not sure it's enough for this trip but if the merino turned out to be not right, I have something else. I think the brand itself comes in several weights. I might be the only person who would take as many underlayer options as real items !
