the magic of merino

moisture wicking

Pulls sweat away from the skin to keep your child dry and comfortable, even during the most active playtimes.

soft & cozy

Made with superfine merino that’s gentle on even the most sensitive skin—no itch, just cozy comfort.

just-right temp

Keeps kids cool when it’s warm and warm when it’s cool, making it ideal for year-round adventures.

easy care

Machine washable and dryer friendly for all those messy moments—perfect for busy families who need gear that keeps up.

better adventures

Your kid's next-to-skin layer is the most important! Designed with extra length to keep up with growth spurts, it keeps kids comfy through sun, snow, and everything in between—so adventures last longer.

better for the planet

Merino comes from our wooly friends, the merino sheep. Unlike polyester/synthetic fabrics that end up in our landfills for hundreds of years (yikes), the iksplorer long sleeve can be composted in six months.

  • 100% natural merino wool—renewable and biodegradable
  • machine-washable for easy care
