The Reima Taitoa Wool Base Layer combines the best of both worlds: wool on the outside for serious warmth and silky lyocell against the skin for maximum comfort. The lyocell inner layer wicks moisture away from skin while temperature-regulating merino wool keeps them cozy even when temperatures fluctuate. Flat seams and strategic stretch panels ensure nothing bunches or chafes, making this the kind of base layer that kids actually want to wear all winter long.
