I always use Ron Hill running tops, find that they are of a very high quality. Baselayers are a mix of Nike and Decathlon. The Decathlon baselayers are very good. Don’t usually bother with a jacket unless it’s really really bad weather. And then it’s an Lidl/Aldi one I bought years ago.
Shorts I have to have pockets in to hold car car key, work ID badge etc.
Socks are very important, I use very slim running socks bought from Run4it, can’t remember the brand, but everyone will have their own preferences. I found that the thicker the sock the less comfortable my feet were.
Gloves are Aldi running gloves and I have a Nike running headband for subzero temperatures. I look like an idiot but at least my ears are warm!
Again the more technical the kit the beter the running experience but no need to spend a fortune unless you are going to be very serious about your running.
