Leather is never light, but it is almost always beautiful - especially if formed in Firenze:
The Pratesi COSTANTINOPOLI costs a little over 100 euros per pound. The price is hefty but, for a leather bag, the weight is not, at about 5 1/4 pounds. I believe I poked my head in this shop in Florence last year. The prices, I’m sure, left me light headed. Suffice it to say there’s a lot to tempt anyone at Pratesi.
