Where can I buy longer length men's chinos with a 30 inch waist?

[Sunflower6]

My 15 year old son is very tall and slim. The last chinos I bought him were next men's 30 inch waist long leg. He needs the extra long leg now but the smallest waist they come in is a 34 inch which is too big for him.

Does anyone know a shop that sells extra long leg chinos in small waist sizes?

You could try Dockers? They tend to wear well too. If you don't want to go to the faff of ordering online, I'm fairly sure places like Debenhams stock them.

Dh is tall and thin, and its very difficult. He got some nice chinos in Gant.
