This is a stretch type with Mochi-hada brushed fabric. Despite the generous brushing, it looks sleek. Because it's finely thick, it won't show through outerwear and won't make you look bulky. Also, the U-neck design makes it difficult to see from the collar of a shirt. Recommended for fishing, touring, those who work in severe cold, and those who work in refrigerators or freezers.
