Lots of layers that you can put on/take off where necessary (warm trains etc., but cold station platforms).
I only do a short commute at each end, and try to integrate items with my office clothes as much as possible, as we don't have much in the way of washing/changing facilities at work. Not much of my stuff is specifically cycle oriented other than the Hi-Vis
- Cotton vest base layer with integral bra (from Uniqlo, I have loads of these and they are back in stock for the spring now)
- Smart fitted black t-shirt and a-line mini/knee length wide skirt or black trousers
- If wearing a skirt, black opaques
- padded cycling 3/4 tights underneath the skirt or trousers (crazy London potholes)
- knee high leather boots with a rubber sole (pedals wreck heels). I keep smart shoes in the office under my desk, as well as a plain black suit jacket
- a velour zip up tracksuit top from M&S
- nice warm scarf
- Hi-Vis Altura Kinetic jacket (quite thin)
- If it is REALLY cold, I might pull out the Gore beanie under my helmet but I prefer to do that on the way home only as it gives me seriously flat hair (and I only have a pixie crop as it is).
I haven't had any more colds (fingers crossed) since before I started commuting in January (I had a very nasty flu over Christmas).
When I get on the train I undo the Hi-Vis, loosen or remove the scarf, and unzip the velour tracksuit top to let some air in.
There have been a few times I have felt cold but it wasn't when I was cycling, it was when I was waiting in between trains and Twickenham station is a bit of a wind tunnel.
I have found advice from elsewhere on the forum to slow down a bit at the end of the journey works really well to stop too much sweating - otherwise you don't sweat too much and then you stop and whoosh .....
