Nuckö Softshell Onesie

Kids softshell onesie in Thunder, black with a magenta wash on one sleeve.

  • Three layer softshell, 10,000 mm rating
  • Reflective stripes for dark mornings
  • Made to order in Estonia by Nuckö
  • For weather down to 6 °C below zero
Details

Thunder is mostly solid black, with a mottled magenta and black speckled wash printed on one sleeve and repeated inside the hood. The asymmetry is deliberate: the print reads at a distance without covering the whole child.

The mainly black body hides mud and wear better than the lighter colourways, which helps on daily kindergarten walks. Made to order in Estonia, 1 to 3 weeks.

Material

94% polyester and 6% polyamide softshell, three layers bonded together: a water repellent face, a thermoactive middle and a brushed fleece inner. Rated 10,000 mm waterproof and 5,000 g/m² a day breathable, which is what makes it warm without being airless.

Maker

Nuckö designs and sews children's outerwear in its own Estonian workshop. Most sizes are made to order rather than held in stock, which takes 1 to 3 weeks and means nothing is cut that nobody asked for. Reflective detailing and softshell construction across the range.

Size & Fit

Eight sizes, by child height in centimetres: 74/80, 86/92, 98/104, 110/116, 122/128, 134/140, 146/152 and 158/164.

The waist adjusts and the cuffs and ankles are ribbed, so a size bought with room to grow still sits closed at the wrists.

Wear it over a base layer in mild weather and over fleece when it turns colder.

Care

Wash as rarely as the suit allows, turned inside out with pockets emptied and every fastening closed.
30 °C on a gentle or sports cycle, mild detergent. No fabric softener and no bleach: both strip the membrane.
Air dry on a hanger or rack without wringing. Keep it out of the tumble dryer and off the radiator.
