The Echadh Seam Top, which has now become a seasonal staple, is a wonderful upgrade and a great alternative to a basic tee shirt. Echadh is a Hebrew word meaning ONE and suggests a composite oneness. As the name implies, the body of the top is made with a single center back seam, no side seam and no underarm seams; as such there is very minimal cutting into the fabric, making the top much more durable that a traditional cut and sew knit top. The fabric Composition is 65% Cotton, 33% Rayon and 3% Elastine. The seams on the sleeves intersect with the shoulder seams on the body of the garment creating a continuous anatomic line from the cuff to the neckline.
