Evisu Top Section:
All Evisu jeans are made of vintage selvedge denim. This means that the denim is made on old style shuttle looms rather than modern projectile looms. In simple terms this means that the cross thread in the weaving process goes back and forth during the weaving process. But modern looms, shoot each cross thread through individually, hence the edge of the cloth is frayed rather than clean (although brands who are only interested in making quick money, try to cash in by faking the smooth selvedge by stitching up the frayed edge afterwards).
No shuttle looms have be made for over 40 years as they can only make cloth about 30 inches wide whereas projectile looms can make fabric 60 inches or even wider for much less money. All the looms that make Evisu denim are practically antiques and about as reliable as a 50 year old car. Because the fabric made on these looms is so narrow we need approximately 3 yards to make each pair of jeans. To maximise the usage, the traditional method was to have a straight outside seam and cut right up to the selvedge so that when you turn the jean up you see the two selvedge edges of the denim stitched together. You can also see it on the inside of the coin pocket.
