Boys' Plus Fit Slim Leg Waist School Trousers (2-18 Yrs)

Product code: T764791P

About this style

School days stay comfortable with our Plus Fit school trousers, designed in a plus fit through the waist and body with an extra 6cms for extra comfort. The slim leg styling creates a modern, streamlined look, while the crease-resistant fabric helps creases fall out easily and the stain and weatherproof finish keeps them looking smart with minimal effort. An adjustable waistband offers a secure, flexible fit, and clever grow-proof hems can be unpicked and pressed down to reveal an extra 3cm in length — helping them last that little bit longer.

Slim Leg Shape – a flattering trouser that is narrower in the leg. Plus Fit- 6cm wider through the waist and/or body.

Great quality. As trousers have an adjustable waist and length this gives a longer life/ use.

It has been a nightmare finding trousers for my youngest. These M&S pair have been a lifesaver. Not only were they one of only few brands that had available product but also had Plus fit as an option. Whilst not a large child, my son is very muscular and has a large bottom and thighs. These fit him really well and the quality felt really good so they should last!

Super trousers no splitting seat area.

My grandson is tall and slim but has a larger backside. Regular size trousers fit on the leg and waist but are too tight on the bottom. Tried these and they are perfect. Roomy enough on the seat area and the waist can be tightened enough so they fit him and don’t fall down. Glad to have found them.

Great style. My grandson tells me the extra width round the waist makes them comfortable. I also like the fact they will grow with him as I can let them down.

My son is age 15, but very tall and broad. I struggle with getting trousers to fit, but these are perfect. Good quality and wash well. Only problem is that the hem seems to fall down.

We found the trousers well sized and with the option to pull in waist or let out which was helpful. Good colour. Good material.

I always buy these trousers for my boys due to the quality and the ability to adjust waist size as their weight fluctuates throughout the year. The slim leg looks smart. I am disappointed in the material as it doesnt seem the same as the ones i ordered past year. For the cost per pair quality shouldn’t be compramised. I will have to see how well they wear.
