Extra long leg, perfect!

Yes, I recommend this

Great fit for a rapidly growing, slim 12 year old boy. Shame you can't get a slim leg version for girls too.

Perfect!

Just as expected. My son is tall and quite slim so the longer length trousers are great. Perfect fit.

Good for tall teenagers

Yes, I recommend this

Good school trousers, have to order extra long long for my tall son with small waist. I do wish that they would start adding the actual leg length to description.

Replacement trousers

Yes, I recommend this

Good quality trousers, better material than some others. Bought to replace ones bought in September, would be good if knees had more reinforcment as thats the only issue.

Long legg trousers.

Yes, I recommend this

The trousers fit very well. They were bought gor school uniform. They are for a 6ft 15yr old so although the waist is a bit bigger than his the adjustable waistband works wonderfully. I would recommend these trousers to anyone.

Great option for the taller child!

Yes, I recommend this

These are the only school trousers (at a sensible price) that I could find to fit my slim, 6ft tall 12 year old. He is happy to wear them although finds the (pricier) adult trousers more comfortable in terms of the fabric quality and overall fit.

Good quality. Good fit on my very slim son once the waist has been adjusted. It would be nice to be able to get a smaller waist in the Slim Leg, Longer Length trousers
