Boys’ cotton round-neck undershirt

Boy’s cotton undershirt

Essential for everyday wear, this boy’s cotton undershirt is designed to provide comfort and softness throughout the day. Lightweight and pleasant to wear, it slips easily under clothing to accompany children at school, at home or during their activities.

Thanks to its cotton-elastane fabric, it offers good elasticity and naturally adapts to the body’s movements, creating a near-second-skin feel without restriction.

Comfort & quality

Made in Portugal, this tee belongs to the Impetus Junior collection, known for the quality of its underwear. The brand applies the same exacting standards as its adult collections, with particular attention paid to materials and finishes.

Its soft, breathable knit lets the skin breathe while providing reliable everyday support.

A discreet, practical essential

With a fitted cut and a round neck, this undershirt slips easily beneath any outfit. Without an inner tag, it reduces rubbing for greater comfort.

Easy to put on and care for, it quickly becomes a wardrobe staple for children.
