I bought a Gore Countdown AS a couple of months ago when it became clear the summer wasn’t going to happen. Very nice piece of kit, windproof and showerproof (kind of) it keeps me just about right at the moment, used most days for commuting. Used with some Alp X waterproof shorts (OK, so I’m a bit of a Gore fanboi) it’s perfect for the weather we’ve got at the moment (chilly, damp/wet, windy).
I wore both on Saturday on a killer loop in the Black Mountains, wether was pretty miserable and the only time I felt cold was off the bike for more than 10 minutes at the top of a very windswept climb, and that was just through the vented back.
I’d recommend.
