I bought some of these in a Kuhl store in the USA on a work trip. They are made from a soft, comfortable fabric with a slight stretch - I absolutely love them. They give you the feel and ease of movement of jogging bottoms whilst looking smart-casual. The two subtle cellphone pockets, one on each leg, are excellent and it feels slightly weird wearing other trousers which don't have them now. Cellphone on one side (iPhone 8 Plus in a case fits fine), sunglasses case in the other. Or your wallet if sitting at a restaurant and you don't want it in your back pocket. Practical trousers which look and feel normal. In the USA, they are available in a range of colours - I really hope Kuhl make those available here in the UK too. I can't comment on longevity as I've only had them about 6 months , but so far I highly recommend them. Credit to Kuhl for not overcharging on the £ price - they are about the same as the USA $ price by the time you add US sales tax in most states.
