We need extra long! Please don’t discontinue!

We needed string bean size trousers. Great you get the length but the waist is still correct and has elastic to adjust. The only flaw I’ve noticed with these trousers (I’ve got two boys) is the metal front clasp is prone to breaking. Think this is also down to boys being lazy and just pulling the trousers apart, rather than pushing them in to unclip but maybe it could be looked at?

Nice but not as good as other trousers previously

Originally posted on marksandspencer.com (UK)

Always buy my son’s school trousers from M&S because of the excellent quality. My son is very tall for his age so bought these longer trousers. The material is quite different in quality to the previous ones I’ve bought - these are thinner. They was up lovely but it is a lot harder to iron creases out. It’s disappointing that I can’t buy the ones I love in a longer length.

Finally found some trousers that fit my son. Had to go a couple of years up in size but the longer leg is great.

Perfect school trousers

Originally posted on marksandspencer.com (UK)

I've been buying these for my boys for years. Great quality - always make use of the additional hem so they last a bit longer through growth spurts. Adjustable waist is ideal when you have children with long legs for their age.

My son is 13 and 6ft 3in. I did take these down (there are extra seams) so they were even longer and should last. Great quality and price.

My lad is pleased. He's very tall and skinny for 16 and this particular trousers fit him perfectly. Got elasticated waist and decent material. I have recommended to other people i knew and really chuffed with it.

Perfect trousers

Originally posted on marksandspencer.com (UK)

Yes, I recommend this

My son is 17yrs , 6'2" tall and slim build. These are the only trousers that fit him like a dream. And what's more impressive is M&S designers have thought through every pain point/requirement to make the perfect school trousers there can be. They are stain and weather proof , crease resistant , have an adjustable waist ( super helpful, In my opinion all trousers should have this ) and icing on the cake is that they have grow proof hem . And the cost doesn't hurt the pockets at all. They have nailed it.

Originally posted on marksandspencer.com (UK)

Perfect fit as described. Lovely material because some of the other M&S boy styles are horribly synthetic which I returned wheras these are brilliant. Highly recommended. This is the second time buying this style. Both my boys have it. Will buy again, no hesitation.
