Shell pants that grow 1.5 sizes
Our flexisize pants, made of 100% recycled polyester, are one of our most popular products!
By using the buttonhole elastic on the inside leg, our flexisize pants can expand by up to 1.5 sizes from the size indicated. Buy your child’s current size and adjust the length as your child grows. When it’s time for a younger child to inherit the garment, just adjust the size. Now that’s what we call practical!
NOTE: The pants come fully expanded, which means they have to be shortened to the indicated size in order to be able to adjust the leg length as desired. The original size of the pants is indicated between the red markings on the buttonhole elastic. Please note that the pants have two adjustments in each leg to ensure the best possible fit.
The shell pants are soft and slick, and made of wind and waterproof fabric. They are made of durable fabric with good breathability, letting out excess heat and moisture. The fully taped seams make them completely waterproof. The pants have adjustable and detachable suspenders, and an adjustable waist. They also have pre-shaped knees and elastic cuffs for freedom of movement and the perfect fit. The fly closes with press studs and a zipper. The replaceable stirrups help to keep the pants in place. Size 134-140 is without stirrups.
The garment comes fully expanded.
Layer 3 - outer layer that retains warmth and protects against all weather conditions.

We’ve had sustainability in mind since the start in 1976. That means we’ve been designing and developing high-quality and long-lasting clothes for almost five decades.
What does sustainability mean to us? To continuously strive to develop and improve every detail, from washcloths to tiny threads, in order to constantly make conscious choices and reduce our impact on people, animals and our planet.
The best thing we can all do to conserve our planet’s resources is to wear our clothes for longer. For as long as humanly possible. To look after them properly. And mend them when they need repairing. We want to help you with all that. So we’ll continue to design high-quality clothes that can be worn, washed and loved for a long time. Clothes that, as soon as one child outgrows them, can be passed on to the next child. And the next. That’s what sustainability means to us.
