Just been rumaging through a bag of old clothes and found a Kerbdog shirt (that I've obviously not missed!), so if anyone is interested, make me an offer.
It's the 'Dry Riser' one mentioned above. Size XL. Excellent condition, it looks worn only once or twice if at all (I never wore it, having bought it on Ebay years ago. I've no idea if it was new or second hand, it's hard to tell with old t-shirts).
Check out my Ebay profile (fyfe79), it's 100% positive so no fear!
