Boy´s seamless long sleeve base layer top Kilpi NATHAN-JB

Description

When your child heads out for skiing, running, cross-country or a ski touring approach to the trail, this is the top you reach for as a base layer that stays dry and never rubs. NATHAN-JB is built for skiing, running, cross-country, ski touring and hike and travel, when activity level changes from minute to minute. The long sleeve and round neck make it easy to layer under a jacket or fleece.

  • No rubbing or irritation on the skin: SEAMLESS knit construction sits close to the body without seams that dig in under backpack straps.
  • Dry and warm during intense effort: OPTI-DRY fabric quickly wicks away sweat, keeping your child dry and comfortable throughout the activity.
  • Freedom of movement on the slopes and on the climb: elastic knit with a high proportion of elastane moves with every motion.
  • Quick drying and a warm feel: quick-dry finish combined with a warming fabric treatment.
  • Fits neatly under other layers: slim fit, long sleeve and round neck without bulk.

Suitable as a base layer for winter sports and travel. Available in several sizes.
