Got a showerproof cycling top from Lidl in Penge yesterday - just under £8 knocked down from £10 or so. Very small when packed into its own pocket. Maybe not very breathable or ultra waterproof but it has a hood - will be great for messing around on camp as an extra lyer/showerprood top - I lost a great Karrimor Pertex top and the
Altura thing I replaced it with is a bit too race-cut for general purpose use. Went for the large size rather than medium which is a bit tent-like but it won't be used for determined riding. Also of course not a disaster if I singe it when cooking.
I think it must be a remainder from a cycling promo I missed a while ago.
