The flatlock seams are designed to protect his skin from chafing, and the interlock knit is luxuriously soft and breathable to keep him comfortable for long days on the trail or slopes.

True to size

This Smartwool base layer keeps my kids warm and dry while out in the elements. Fit runs true to size and sleeve length ends just at the wrist. The material is soft against your skin and wicks moisture away while still keeping you warm. Great staple piece to have for winter activities.

Stylish merino mid-layer for boys

Runs small
Size Bought

Got this for my son as a mid-layer for cold days outdoors. I have a hard time finding nice wool products for kids (Ibex, Smartwool, Icebreaker).. This one is beautifully made with great fabric but runs really small. He is right between youth medium and large for most clothes but we got this as a large and it is really small. Sleeves end well short of wrists. The large is more liken a boys medium. We returned. Would re-ordr if they had extra large - but they don't.
