I got two used norgie shirts on ebay for 7.99 the other day, to use for cycling to and from work in the winter. Tried one out today, wearing it under my rowing waterproof instead of the usual cotton long-sleeve t-shirt and cotton sweatshirt. It really did the business - it kept me warm for the first couple of miles that are gently downhill, where there's extra windchill but little effort to warm myself up. On the uphill bits I didn't overheat, and when I got into the gym changing room I found that I hadn't sweated as much as I would have normally.
Top kit! Will think about getting some brand-new ones for less sweaty activities.
