If your little boy likes long days outdoors on cool days or romping around in the snow, slip on the Icebreaker Boys' BodyFit 200 Oasis Legging under his pants. Merino wool insulates and breathes so he stays comfortable whether the wind whips or he is huffing up a sledding hill. The UPF 50-rated fabric provides extra sun protection while an elastic waistband helps the leggings stay put. The jersey knit feels soft and comfortable against his skin. The legging can be worn multiple days without laundering since merino wool is naturally anti-microbial and does not hold odors―easy for you, easy for him.
