This is a high performance, twisted multifilament polyester outdoor thread that is perfect for sail and canvaswork. Sunstop^® polyester thread has advanced UV protection that is specially designed for outdoor applications where seam strength and fade prevention are required. Sunstop Thread also features a non-wicking finish that helps to reduce moisture coming through seams. This polyester thread very seldom frays at the needle eye, and the consistent bonded finish minimizes the need for continual machine tension adjustments. Perfect for use on sails, tents, boat covers, awnings, outdoor canvas covers and tarps.

Use this Tex 90 thread with a #18 or #20 needle on 6–10 ounce fabrics (including all Sunbrella^® fabrics). We recommend a #20 needle when sewing with the Sailrite^® Ultrafeed^® Sewing Machine.

Sailmaker's thread should pull up off the top of the cone for a smoother feed to the sewing machine and to add an extra twist in the thread. The extra twist increases thread strength, helps keep the thread from unlaying, and eases tension problems.

Please Note: Thread color looks much darker on the cone, but once sewn the color blends to an almost perfect color match. The color is designed to change after the bonded coating passes through a sewing machine.
