"This is my second trip with packing cubes, but first time I've used the PCBP as a backpack... or to be more accurate as a back-of-my-chair-pack! It was pretty warm here, in Spain, today (for February) at about 26º (80º in old money) so it was definitely T-shirt weather, but we live about 15Km (10miles) in from the coast and we were heading down to the coast to meet friends for an afternoon coffee. It can be chilly down there and, when the sun goes down, decidedly cold, so we went prepared. With 2 jumpers and my down waistcoat, what better than the PCBP?"
