Hi, Can you give some suggestions for some v neck long sleeve merino wool sweaters that work for travel? I'm looking for a piece I can wear with just a tank or a long sleeve t shirt to add warmth. Also, any suggestions for a 3/4 length pack able light down coat for travel. Have you ever tried the Uniqlo brand down jackets? I know I reada post for what you wear on the plane for long trips but I can't locate it anywhere. Thanks so much for your help.
