Merino wool has long been the tried and true pinnacle of layering materials. It has a crazy warmth-to-weight ratio, it's breathable and moisture wicking, and it stays warm even when it gets wet. Combine that with the power of Helly Hansen's house blend moisture management tech and you can imagine you're getting your kid just about the best snowsport base layer you could get your hands on, or their elbows into. The Helly Hansen Lifa Merino Midweight Baselayer Set is so comfy they might not want to take it off.
