Im not arsed about fancy makes for work, i wear shorts 80% of the year and i really prefer holster pockets to put notes/pen/cloth/gloves etc.
Then i got a pair of these 2 years ago from my local lidl £15 
They are brilliant for winter, really thick, warm thermal trousers.
same as these

If you bought a pair of mascot advanced trousers, I'd be confident when you buy trousers after that you wouldn't buy anything else apart from them.
You probably spend more time in work clothes than normal clothes during the week. Spending extra on trousers that are alot more comfy to wear and makes your movement alot easier when wearing them is worth the money imo.
A guy who used to work for me used to say I was mad because I buy nike air max to wear at work. I'm on my feet most of the day and there really comfy to wear. I'd counter that argument and can't understand why people would buy cheap ones that aren't as comfy just to save some money.
The people who won't spend more money on work gear that will make there working day feel more comfortable, will have an electric reel and can't understand why others wouldn't have one as it makes there day more comfortable working. It's the same scenario, but they have a different outlook on the 2 scenarios.
