I highly doubt a wool sweater, or pair of wool trousers will even come close to having 8 yards of wool, the other thing that you have to remember is the sheer craftsmanship involved in making a 16oz. hand sewn wool kilt. Given the work that goes into a kilt like that I would say you are getting a bargain at twice the price, also remember that your trousers or sweater will not even come close to lasting as long as a kilt, my first kilt is close to 60 years old and can still be worn. Expensive I think not.

As far as Utilikilts go not my cup of tea, but to each their own.
