The sweater that outlasts the size. Rib knit from 100% merino wool, the Hopu Top is the layer parents come back to season after season. Warm enough for forest school and ski days, slim enough to disappear under a snowsuit, and soft enough that even sensory-sensitive kids wear it without complaint. Size up and cuff the sleeves - most children get two to three years out of a single top, and many are passed on to younger siblings still in great shape. It breathes, regulates temperature, and resists odour naturally - so it goes weeks between washes no matter how hard it's worn. Features Rib knit expands with growth - designed to be sized up and cuffed Temperature regulating - warm as a standalone, low-profile enough to layer under snowsuits and jackets Naturally anti-odour - rarely needs washing Sensory-friendly - soft enough for sensitive skin, zero itch OEKO-TEX® 100 certified free from harmful chemicals 100% merino wool — chlorine free, mulesing free Sizing note The Hopu is designed with generous sleeves so you can size up and cuff, extending the life of each top across multiple seasons. Most parents size up one size and cuff the sleeves - the rib knit keeps the cuff neat and close to the wrist rather than bunching. Composition 100% merino wool - chlorine free, mulesing free.
