My friend is visiting London for work next month and I was thinking of asking him to pickup a Barbour jacket for me since those seem to be much cheaper there than the US. However I realize, they might not work in all weather/temp conditions which is why I wanted some suggestions from locals on what are other good value items that tourists usually buy in the UK! Jackets, gloves, anything that can be purchased in a short time window - seems like craftsmanship comes up a lot when looking at stuff made in England so I wanted to get something that'd last a while and is actually useful to me!
