Leather Ryanair Cabin Bag

[crimsonlake]

Son's birthday comimg up and he has suggested a 40x25x20 cm Ryanair cabin bag, not rucksack as a gift. I have been searching, but such a bag does not seem to exist.
Can anyone suggest where I may find one.TIA

I have just bought 4 from amazon.i think the brand was '5 cities" dd bought one from argos 'IT' brand

Ah, I should have made it clearer that I am looking for a leather cabin bag in my post, but thanks.

Lakeland leather.
Some beautiful ones.

Moier - Found almost just the one on Lakeland but it's a few cm's over Ryanair's cabin measurements, so frustrating!
I have been searching for ages and this is the closest I have found thanks to you.

Slihtly off piste and a little smaller but might well work -my father used something similar for years https://www.medisave.co.uk/products/elite-classy-s-medical-bag-brown-leather?currency=GBP&variant=44873836331291&utm_source=google&utm_medium=cpc&utm_campaign=Google%20Shopping&stkn=34c6ddfaad06&utm_medium=adwords&utm_campaign=&utm_source=&utm_term=&gad_source=1&gclid=EAIaIQobChMIr7W7yK3ohwMVr5BQBh3LRS0wEAQYECABEgLV1_D_BwE

No idea about the quality https://www.lukecase.com/products/leather-duffle-bag-1028?currency=USD&variant=41969583980707&utm_source=google&utm_medium=cpc&utm_campaign=Google%20Shopping&stkn=cff133e72003&srsltid=AfmBOooTvDZIYyZ7mGNuJlvd9kouv-9v55QAI1RyS0kNFyHJT4eld6bTpyE

Technically too high but I guess so long as he didn't over fill it it would be eas enough to squash it down in the frame https://www.etsy.com/uk/listing/474407386/brown-duffle-bag-travel-bag-leather?gpla=1&gao=1&

Some of these meet Ryanair's 55 by 40cm
