2 NEEDLE BOTTOM COVERSTITCH - ISO 406

You'll find this seam on the used on the bottom opening and sleeve cuffs on our knit products like the T2 WerkFleece and T.5 WerkTee and WerkPolo. We use this seam because it lays flat while maintaining most of the stretch of the fabric -- making it both comfortable against your skin and easier to don or doff the garment.
