What Our Gearhead(R) Experts Are Saying: "This set is my go-to for layering my kid on chilly mornings. The Tencel and merino combo feels luxuriously soft while managing moisture like a pro-no itching, no complaints, just happy playtime warmth that lasts all day." We want our kids to love being outdoors as much as we do, and the Kari Traa Hennie Set helps make that happen. Crafted with a blend of naturally breathable merino wool and silky-smooth Tencel(TM) lyocell, this base layer delivers lightweight warmth that keeps up from breakfast to bedtime. The Hennie Set feels soft against sensitive skin while wicking away moisture to keep little explorers comfortable through every snow fort, sled run, and cocoa break. Sustainable and renewable materials give us peace of mind, while flatlock seams and a flexible waistband make for easy layering and all-day comfort.
