I'm trying to hunt down a very particular type of outdoorsy top, which is proving really hard to track down through online shopping, presumably because it isn't one thing or another. It's not a hoody or a fleece or a coat! Basically, I want a light top/jacket, with a full-length zip, but ideally without a hood, which is 100% cotton or thereabouts - so not a fleece. It's to be worn over a t-shirt for summer walking and needs to come in larger sizes as I'm size 16-ish. If anyone has seen anything similar at a reasonable price I'd be very grateful!
