The Seniq Warmup Merino Turtleneck Baselayer Top is a long-sleeve base layer top made from 100% merino wool. Articulated patterning allows unrestricted movement, and the body-skimming fit makes it a layer for winter hiking and skiing. What Our Gearhead(R) Experts Are Saying:"The turtleneck stayed soft against my neck on cold days with no itch, and I pulled the sleeves down through the thumbholes before heading out. I started each cold morning with my neck and hands covered."
