My husband and i swear by Mavi Jeans. Its a Turkish brand, you can buy them online worldwide but i tend to buy them in Turkey where they are very cheap, about 20Euro. Lots of different wash and fit, usually contain some lycra. Both ours have lasted 3+ years so far with moderate wear, they keep their colour and shape beautifully. Thats a lot longer than my ethical organic jeans, which is all washed out and beginning ro wear thin round the bum
